PolyU Jockey Club Design Institute for Social Innovation and EdUHK Xiqu and Intangible Cultural Heritage Centre jointly submit Policy Address Recommendations; Proposing two pivotal cultural infrastructure projects in Northern Metropolis to promote urban-rural integration and community making

The Jockey Club Design Institute for Social Innovation (J.C.DISI) at The Hong Kong Polytechnic University (PolyU), in collaboration with the Policy Research Centre for Innovation and Technology (PReCIT), the Department of Building and Real Estate, and the Xiqu and Intangible Cultural Heritage Centre at The Education University of Hong Kong (EdUHK), today submitted their recommendations to Dr Stephen WONG, Head of the Chief Executive’s Policy Unit at the Central Government Offices of HKSAR for the 2025 Policy Address. Titled “Living Intangible Heritage: ‘Cantonese Opera and Intangible Cultural Heritage Archive’ and ‘Northern Metropolis Cultural Trail’ as Urban-Rural Integration and Community Making Initiatives in the Northern Metropolis,” the proposal advocates for cultural preservation and community engagement in the region. J.C.DISI hosted the “Northern Metropolis Future Forum” in early July, which attracted nearly 500 participants. The Forum featured keynote speeches and roundtable discussions where academic and industry leaders from Mainland China and Hong Kong shared their views on some highlights of the Chief Executive’s 2022 and 2023 Policy Addresses regarding the development plan of the Northern Metropolis which included developing “landmark cultural facilities” and establishing “iconic cultural and arts facilities” in the region. Leveraging these discussions, the proposal integrates expert insights from the Forum with professional expertise of PolyU and EdUHK scholars, focusing on two pivotal cultural infrastructure initiatives in the Northern Metropolis: Establishing the “Cantonese Opera and Intangible Cultural Heritage Archive” Echoing the initiative of providing iconic cultural and arts facilities in the Northern Metropolis raised in the Policy Addresses, the proposal recommends establishing Hong Kong’s first “Cantonese Opera and Intangible Cultural Heritage Archive” in that region, most ideally located close to local villages, to help foster urban-rural integration and community making through Cantonese opera. The Archive should move beyond a traditional museum model of simply displaying cultural artifacts. It should instead provide visitors with immersive experience of the cultural context of Hong Kong’s rural villages through spatial design that incorporates both diverse village characteristics and elements of daily life, with an aim of creating an interactive platform where traditional culture is integrated into everyday life. Creating the “Northern Metropolis Cultural Trail” It is advised that the Government conducts comprehensive research into public spaces in the region that are used as performance venues for “Cantonese Opera for Appeasing Gods” during traditional festivals, such as important historic buildings, and connect them with the routes of village parades for traditional events such as Jiao (Da Chiu) and Xingxiang (burning incense in a prayer service) , as well as with existing heritage trails. This will enable the creation of an unique cultural landscape that helps promote both preservation of traditional village culture and distinctive local tourism. Prof. LING Kar-kan, PolyU Interim Vice President (Campus Development and Facilities) and Director of J.C.DISI, commented, “The two proposed initiatives not only proactively revitalise intangible cultural heritage, but also serve as pioneering models of cultural infrastructure in Hong Kong, highlighting the unique cultural soul of the Northern Metropolis. This aligns with the industry-led development approach and responds to the notion of building iconic cultural and arts facilities. The recommendations also respond to the Nation’s 14th Five-Year Plan, which positions Hong Kong as an East-meets-West Centre for International Cultural Exchange—suggesting using Cantonese opera not only as a cultural bond to foster urban-rural integration, deepen community making and nurture local creative talent, but also to develop sustainable cultural tourism. We believe that the momentum of large-scale urbanisation in the Northern Metropolis can be channelled into a force for preserving and perpetuating traditional culture.” Prof. LEUNG Bo Wah, Executive Director of the EdUHK Xiqu and Intangible Cultural Heritage Centre, stated, “At the Northern Metropolis Future Forum Roundtable, experts from fields including Cantonese opera and joss house arts, intangible cultural heritage preservation and promotion, built environment, engineering and innovation, cultural research and sustainable development, heritage conservation, rural revitalisation, placemaking, creative tourism, and social innovation reached a consensus. They agreed that the ‘Cantonese Opera and Intangible Cultural Heritage Archive’ should adopt a living heritage approach, integrating Cantonese opera and intangible heritage into everyday life and creating participatory cultural spaces for the public. Meanwhile, the ‘Northern Metropolis Cultural Trail’ would connect suitable Cantonese opera performance venues and traditional villages, restoring cultural threads severed by urban development and enabling the continuation of traditional festive activities amid urbanisation.” The proposal also suggests leveraging digital technology to enhance preservation of cultural heritage, including through the establishment of a Cantonese Opera Digital Archive for the Northern District, development of immersive experience technologies and the setting-up of an interdisciplinary innovation lab to explore the integration of Cantonese opera with modern industries. Furthermore, the proposal addresses urban-rural integration and cultural talent development in the Northern Metropolis. It suggests launching a cultural integration programme to facilitate interaction between local and incoming residents through cultural heritage activities, as well as establishing a Cantonese opera talent development system that covers basic knowledge and professional training. These initiatives aim to advance the sustainable development of the new community, and build a comprehensive cultural conservation and innovation ecosystem. With regard to funding, the proposal recommends harnessing existing government resources such as the Countryside Conservation Funding Scheme, the Lantau Conservation Fund, as well as the resources of the Arts Development Council and the Culture, Sports and Tourism Bureau, while also exploring innovative funding models like public-private partnership matching funds and social impact bonds to help ensure the sustainability of the initiatives. Prof. Eric CHUI, Co-Director of PReCIT and Head of the PolyU Department of Applied Social Sciences, expressed his hope that “Government, academia and all other sectors of society will work together to advance cultural conservation in the Northern Metropolis, creating a livable environment with a strong sense of belonging and identity for the 2.5 million future residents, while also enhancing Hong Kong’s international standing as an East-meets-West Centre for International Cultural Exchange.” This proposal by J.C.DISI focuses on issues of urban-rural integration and community making in the Northern Metropolis. Meanwhile, PReCIT will separately submit recommendations for the 2025 Policy Address on other aspects, such as innovation and technology, research and development, and talent cultivation. Through these efforts, PolyU aims to assist the Government from multiple perspectives in formulating forward-looking policies to drive the comprehensive development of the Northern Metropolis. ***END***

PolyU initiates cognitive remediation programme using memory encoding strategies to provide early intervention for people with mild cognitive impairment

With its ageing population, the prevalence of dementia in Hong Kong is expected to increase. Healthcare researchers from The Hong Kong Polytechnic University (PolyU) have developed an innovative mobile application-based cognitive remediation programme, Enhancing Memory in Daily Life (E-MinD Life), targeting those who experience memory complaints, mild cognitive impairment (MCI) and mild dementia. The programme, leveraging memory encoding strategies, provides early intervention to delay the functional deterioration associated with cognitive decline, supporting these individuals’ independent living and enhancing their quality of life. As individuals age, cognitive functions and memory gradually decline, affecting their ability to perform daily activities independently. Such memory decline is more pronounced in people with MCI. MCI is a significant area of interest in ageing and dementia research, and, more importantly, various studies suggest that it can indicate early dementia-related neuropathological changes years before a clinical diagnosis of dementia. Among the three stages of memory, namely encoding, storage and retrieval, the encoding stage is often the first to be affected in people with MCI, causing memory decline. Developed by Prof. Karen LIU, Professor of the Department of Rehabilitation Sciences at PolyU, in collaboration with Dr Nikki TULLIANI, Associate Lecturer at Western Sydney University, the E-MinD Life programme is built on the principles of semantic and perceptual memory encoding, and innovatively integrates cognitive remediation into daily activities. As an early intervention, it aims to train older adults in the early stages of cognitive decline, while they still have the capacity to learn new skills and adopt memory strategies to better manage daily activities. The programme lasts for nine weeks, with three 60-minute sessions per week: one individualised therapist-led meeting followed by two self-administered sessions. Humans can register new information to memory through semantic encoding and perceptual encoding of information. Prof. Karen Liu elaborated, “Semantic-based memory, also referred to as conceptual knowledge or declarative memory, encompasses our long-term understanding of objects, word meanings, facts, concepts, rules and people, acquired through our lifetime experiences. While these knowledges are organised into networks of connected ideas or concepts, semantic memory encoding enables us to associate new information with what we already know and remember it more efficiently. Perceptual-based memory encoding, on the other hand, involves capturing and storing visual information, such as images, in memory to help with recall.” As memory decline sets in, people with MCI often have difficulties with instrumental activities of daily living (IADLs), involving essential tasks such as household chores, shopping and managing finances, which are crucial for maintaining their independence in both home and community living. E-MinD Life incorporates semantic and perceptual encoding techniques into 12 common IADLs. These IADLs are categorised into three blocks: “meal preparation and clean-up activities”, “laundry activities” and “communication and community activities,” each comprising four tasks. By engaging participants in these structured tasks, the programme shows significant potential in fostering cognitive engagement and practical learning. The encoding techniques enable participants to organise pertinent aspects like person, place, time and object, and establish connections between these concepts, enhancing learning and memory. The techniques include “visual imagery” and the “method of loci,” which help participants connect visual information from memory; “chunking,” which requires them to break down the IADL into different steps, give context to the chunks of information and then form a contextual story; and “self-generation,” which asks them to use their own words to describe the IADL. Based on a user-friendly mobile application, E-MinD Life utilises knowledge and methods derived from previous research, allows tailoring of the programme to meet participants’ individual needs, and provides real-time feedback. In addition, by reaching out to larger populations, E-MinD Life is able to provide community-based interventions, extending the impact of cognitive remediation programmes beyond professional-led training. Prof. Liu added, “Non-pharmacological treatments are essential for alleviating the decline in memory and cognitive abilities through effective preventive and early intervention measures. Enabling older adults and MCI individuals to easily use E-MinD Life at home, we aspire to create a cost-effective, self-administered and time-flexible means for personalised interventions. By teaching participants to apply semantic and perceptual encoding principles in everyday tasks, the programme supports individuals in overcoming challenges associated with memory decline. This initiative also marks a notable advancement in leveraging memory encoding to facilitate cognitive remediation.” To further refine the administration of E-MinD Life, focus groups and expert reviews were conducted to gain insights from healthcare professionals, as well as from older adult participants and their caregivers. A pilot study on E-MinD Life was conducted in Australia to evaluate its usability. The qualitative analysis revealed that participants found the programme enjoyable and beneficial. Specifically, it increased memory awareness in daily life, stimulated the learning of new skills and technology, and provided an appropriate level of challenge. A Chinese version of E-MinD Life is currently being developed for trial use in Hong Kong. Inspired by their prior endeavours in stroke rehabilitation, Prof. Liu and her team have explored memory encoding for older adults since 2006. After conducting a series of studies to understand the neuro-mechanisms associated with these memory encoding techniques, the findings were translated into clinical projects to assess their applicability within the clinical population. Subsequently, E-MinD Life has been developed with a commitment to promoting cognitive training for older adults in home settings. ***END***

PolyU researchers unveil novel strategy to achieve both strength and toughness in 2D materials design, advancing applications in electronic and photonic devices

The mechanical strength and toughness of engineering materials are often mutually exclusive, posing challenges for material design and selection. To address this, a research team from The Hong Kong Polytechnic University (PolyU) has uncovered an innovative strategy: by simply twisting the layers of 2D materials, they can enhance toughness without compromising material’s strength. This breakthrough facilitates the design of strong and tough new 2D materials, promoting their broader applications in photonic and electronic devices. The findings have been published in the international journal Nature Materials. While 2D materials often exhibit exceptional strength, they are extremely brittle. Fractures in materials are also typically irreversible. These attributes limit the use of 2D materials in devices that require repeated deformation, such as high-power devices, flexible electronics and wearables. Efforts to improve toughness by introducing defects, such as vacancies and grain boundaries, often degrade intrinsic electrical properties, leading to a trade-off between mechanical durability and electronic performance. Therefore, enhancing both the strength and toughness of bulk materials for engineering applications has remained a significant challenge. To overcome these limitations, a research team led by Prof. Jiong ZHAO, Professor of the PolyU Department of Applied Physics, has pioneered a novel twisting engineering approach whereby twisted bilayer structures enable sequential fracture events, addressing the conflict between strength and toughness in 2D materials. The finding was supported by nanoindentation and theoretical analysis. Typical transition metal dichalcogenides (TMDs) is a class of 2D materials known for their unique electronic, optical and mechanical properties. These characteristics enable their diverse application in electronics and optoelectronics, energy storage and conversion, sensors and biomedical devices, quantum technologies, mechanics and tribology. By focusing on TMDs, such as molybdenum disulfide (MoS₂) and tungsten disulfide (WS₂), the team discovered a new fracture mechanism in twisted bilayers. Using in situ transmission electron microscopy, the team found that when cracks propagate in twisted bilayer structures, the lattice orientation mismatch between the upper and lower layers leads to the formation of interlocking crack paths. Following the initial fracture, the crack edges in both layers spontaneously form stable grain boundary structures through interlayer self-assembly. This distinctive “crack self-healing” mechanism protects subsequent fracture tips from stress concentration, effectively preventing further crack propagation. Notably, this process consumes more energy than conventional fracture, and the degree of toughness enhancement can be tuned by adjusting the twist and twist angle. Prof. Jiong Zhao said, “By breaking through the framework of conventional fracture mechanics theory, this study presents the first demonstration of autonomous damage suppression in 2D materials, establishing a groundbreaking strategy for designing integrated novel strong-and-tough 2D materials. This research also extends the application of twistronics to mechanical performance design, such as with regard to material strength, opening exciting possibilities for the development of future electronic and photonic devices. As fabrication techniques for twisted 2D materials continue to mature, a new generation of smart materials combining superior mechanical properties with exotic electrical characteristics, holds great promise for technological innovation in the fields of flexible electronics, energy conversion, quantum technology and sensing.” ***END***

Prof. YANG Hongxia, Executive Director of the PolyU Academy for Artificial Intelligence, Associate Dean (Global Engagement) of the Faculty of Computer and Mathematical Sciences, and Professor of the Department of Computing, has received funding from the Theme-based Research Scheme 2025/26 under the Research Grants Council for her pioneering project, “Collaborative Generative AI (Co-GenAI)”. The project has been awarded total funding of HK$62.6 million, with HK$41.79 million provided by the RGC and the remaining amount matched by PolyU and other participating universities. This initiative is aimed at reshaping the landscape of GenAI through a decentralised way. The research holds significant potential to strengthen Hong Kong’s position as a global leader in GenAI development, with real-world applications in healthcare and technology. Prof. Christopher CHAO, PolyU Vice President (Research and Innovation), said, “We are delighted that our scholar has received this significant support. This pioneering project exemplifies the University’s commitment to advancing cutting-edge AI research, alongside our emphasis on inclusive and sustainable technological development. PolyU will continue to leverage its world-class research capabilities to make a profound impact on the future development of Hong Kong and the global community. With the launch of the PolyU Academy for Artificial Intelligence, we are poised to foster interdisciplinary collaboration and unlock new frontiers in AI applications.” The project, led by Prof. Yang Hongxia, aims to develop a novel collaborative GenAI paradigm known as Co-GenAI. The system evolves through the integration of several hundred domain-specific models to create a foundation model designed to achieve artificial general intelligence (AGI) with significantly reduced centralised computational demand. By addressing the current constraints imposed by graphics processing unit (GPU) monopolies, this innovative approach is set to democratise AI development and enable broader participation in GenAI research and deployment. Co-GenAI is tailored to enhance different domains and collaborations, with the long-term goal of creating a versatile platform for the next generation of GenAI ecosystem. The project’s key tasks include the development of domain-adaptive continual pre-training infrastructure and the design of a robust, generalisable model ranking methodology. In addition, an advanced model fusion approach will be implemented to merge heterogeneous top-ranked domain-specific models. Prof. Yang expressed her gratitude for the RGC’s support and said, “Backed by a team of world-renowned researchers with extensive expertise, we believe Co-GenAI will play a transformative role in advancing the democratisation of AI, expanding its accessibility across disciplines and enhancing cost-effectiveness. We are confident that this novel paradigm will spark greater innovation and diversity in the field, ultimately paving the way for the development of a global foundation model that is both sustainable and inclusive.” To evaluate Co-GenAI, the research team will implement and deploy the system across a wide range of applications in collaboration with industry partners including Cyberport, Hong Kong Science and Technology Park, Alibaba, and leading hospitals such as Huashan Hospital affiliated to Fudan University, Shandong Cancer Hospital, and Sun Yat-sen University Cancer Center. The RGC’s Theme-based Research Scheme aims to pool the academic research efforts of UGC-funded universities to conduct research on topics of strategic importance to Hong Kong’s long-term development. Evaluation criteria include qualification as world-leading by international standards and the potential impact on Hong Kong. ***END***
