Lydia Shum Din Ha is a Hong Kong comedian and actress known for her distinctive body weight. Regularly sporting her trademark dark rimmed glasses, she is affectionately known to peers and fans as Fei-fei (Fat Fat), and has appeared in numerous Hong Kong films.

Lydia was born in 1947, in Shanghai, in a large family of 12 (6 sisters and 3 brothers) and moved to Hong Kong when she was very young. At 12, she learns from a friend that the Shaw Brothers are looking for a young slightly overweight actress. So, she tries her luck without telling her parents. Luckily she is success and made her film debut in 1960, joining Shaw Brothers as a child actress who often alongside Josephine Siao and Connie Chan.

Following this success, she gives up school to devote herself to a film career. She will not regret it! Lydia will be part of big commercial successes in which her glibness and her physical appearance do wonders to make the audience laugh. The emblematic film of that time is House Of 72 Tenants, which will contribute in putting Cantonese back to the fore (in the early 1970s when Mandarin cinema was the norm).

In the 1970 or 80s, she starts to diversify herself, by regularly appearing on television, even more than on cinema screens. Filmwise, she can all the same be seen in the popular series of Mad Mad World and the well-named Double Fattiness.

She hasn't made any films for a few years but she has remained very present in the Hongkongese daily life by appearing on television, in commercials and various great events of the local culture life. As for her love life, she was married to Adam Cheng, with whom she divorced afterwards.

In 2006, Lydia Shum was admitted to hospital for a gall bladder cancer. Then she had heart and lungs complications. Travelling back and forth between house and hospital was her life's routine in the last 3 years. As a sign of will to struggle for life, she treated herself to the life pleasures (especially food...) after each of her illness remission .

The actress died at 60 in the Hong Kong Queen Mary Hospital on February 19, 2008 at 8:35 PM (local time), after 3 years of struggle against a terrible disease. Lydia Shum was not only very famous in Hong Kong but also in all Asia and in chinatowns around the world.
