Her will in 1969 provided that assets valued at HK$3 million would go to the Hong Kong Government for the construction of free healthcare centres and clinics for the needy.

[9] In an article about the life of Fung-shee published by the South China Morning Post in 1972, it stated that she had five brothers, increasing the probability of her being Kwok-tai's daughter.

[10] On 13 October 1969, Yung entrusted the Chartered Bank of Hongkong Trustees Limited to make a will, bestowing HK$3 million worth of assets to the Hong Kong Government, for the construction of free healthcare centres for the needy.

[3][11] Following her death, the Chartered Bank of Hongkong Trustees Limited, confirmed by the Supreme Court in December 1972 as the sole undertaker, discussed with the Medical and Health Department of Hong Kong on how to best use the bequest to fulfil her last wishes.

[2][3] After several years of discussions, the Department decided to build a healthcare centre at Cha Kwo Ling Road, Kwun Tong, Kowloon.

[14] HK$32.5 million was withdrawn to aid the construction of Madam Yung Fung Shee Health Centre (容鳳書健康中心) located at Sai Ching Street, Yuen Long, New Territories.

[14] The centre, which serves primarily Yuen Long residents, is four stories high and provides services such as general outpatient clinic, family health, community nursing, dental and eye care.
