Since the early 1990s, Lau and his Charitable Trust have donated nearly HK$5 billion to various institutions, including numerous individual cases. Major beneficiaries included Education and Healthcare, each account for approximately 20% of the total, while cases for the Under-privileged make up about 10%. The remainder includes categories such as Environmental Protection and Cultural Services. Lau has been a film enthusiast since childhood. In an effort to support the Hong Kong film industry, The Joseph Lau Luen Hung Charitable Trust donated HK$10 million to the "Fresh Wave Film Festival" in 2018, encouraging local young creators with potential who aspire to work in film. During the pandemic, to alleviate the hardships faced by grassroots film workers, the Trust contributed HK$10 million to a Support Programme initiated by the Hong Kong Performing Artistes Guild in 2020. In early 2021, the Trust supported One Cool Group with HK$15 million to cooperate on 5 local film production. In the same year, the Trust donated HK$10 million to the Federation of Hong Kong Filmmakers's "Keep Rolling Keep Running" Programme, aiming to support the industry in overcoming challenges during the pandemic. Since the 2021 academic year, in order to commend underprivileged students who successfully enroll in the 8 major universities in Hong Kong, The Joseph Lau Luen Hung Charitable Trust has launched a scholarship programme. The programme has a budget of approximately HK$1 million for its first academic year and awards outstanding students from the 8 universities, including the HKU, CUHK, HKUST, PolyU, CityU, HKBU, LU, and EdUHK. Through this encouragement, the programme aims to support academically excellent students in receiving a quality education, helping them move toward their aspirations and contribute to society. In 2023, Kimbee Chan, the Director of Trustee of The Joseph Lau Luen Hung Charitable Trust, along with her eldest daughter, Josephine, spent about a week visiting impoverished areas in Liangshan, Sichuan (四川涼山), delivered care and cheers to children by showing support to local girls' education development. In 2025, a medical complex of The First Affiliated Hospital, Sun Yat-sen University was inaugurated. The total investment in the complex exceeds HK$600 million, with a donation of HK$400 million from The Joseph Lau Luen Hung Charitable Trust. The complex was therefore named after Lau (劉鑾雄樓). The complex's opening further enhances the Hospital's capabilities in diagnosing and treating critical illnesses, as well as its emergency medical response and rescue abilities, bringing more resources for quality healthcare services. In addition to establishing a Women's and Children's Centre and the International Medical Centre, the Hospital has collaborated with the Mass General Brigham (MGB) of Harvard University and the Foshan Hospital of Traditional Chinese Medicine to create a Sports Medicine Centre that combines Western and
Traditional Chinese medicine. The Hospital's Intensive Care Unit (ICU) is equipped with VitalGo electric beds valued at HK$600,000, which help improve patient mobility and comfort. Furthermore, the complex also includes an emergency centre, a surgical centre, and a rooftop helipad for emergency rescue helicopters, establishing a 30-minute medical emergency response network for the Guangdong-Hong Kong-Macao Greater Bay Area. Meanwhile, Lau Ming-Wai also made significant contributions to charity and social progress. In 2016, Lau Ming-Wai donated US$50 million (approx. HK$390 million) to the Karolinska Institutet in Sweden, enabling the establishment of the "Ming Wai Lau Centre for Reparative Medicine" in Hong Kong, which is the Institutet's first hub outside of Sweden. == Art and wine collections ==
