Born in October 15, 1892, a native of Nanhai in Guangdong. When Mok was a child, she was adopted by her uncle and aunt who were childless. Later, Mok was secretly trained in Mok Ga by her uncle, despite herself being forbade by her aunt. She also learned Dit Da by him. By 1906, her Dit Da practice was completed and she became an accomplished Mok Ga martial artist.
Folkore basis
According to a common folklore regarding her encounter with the well-known Hung Ga practitioner and future spouse Wong Fei-Hung, in 1911, Wong Fei-Hung and his students were performing lion dance during the Dragon Boat Festival in Foshan, when one of his shoes accidentally slipped out and hit the face of the then 19-year old Mok who was observing the dance. Furious, Mok stepped onto the stage and struck Wong in the face, stated that "This time it's your shoe, but what if the next time it's your weapon. You could have killed someone. A person of your skill should not ever have an accident like that." Wong apologized, "You are right I should not have been so careless." Mok left and disappeared into the crowd. A few days later, Mok's uncle sought Wong out to apologize for his niece's behavior, and the two became friends. Wong and Mok's uncle met countless times and developed understandings with one another. Mok's uncle eventually gave her hand to Wong in marriage.
Historical basis
However, fast-forwarded to Mok Kwai-lan's interview with Andre Lam of Real Kung Fu made in 1976, she made no mentions of that fateful incident, and stated that Wong Fei-hung was a friend to her uncle and they would often had meals and chats at her uncle's house. One day during their conversations, Wong asked her uncle that he wanted to marry Mok, he accepted. Much to her aunt's dismay, who stated that Wong is too old for Mok, and by allowing the marriage to happen Mok's uncle would did a wrong to his brother. Mok and Wong eventually married two years later in 1915 when she was 23 and he was 68. Since Wong's previous wives had died young, he considered himself to be a hex on his wives and had sworn never again to take a wife. Therefore, although she would be his only spouse from the time of their marriage to his death, her union with him was as that of a concubine and not a wife. Wong also taught Mok Hung Ga, and she helped Wong to oversee the operations of his training ground, traditional medicine shop Po Chi Lam, and Dit Da clinic, where she performed all kinds of duties as a shop-keeper, a Dit Da healer, a physician, a cook, and a martial arts instructor respectively, leading a busy life. After the death of Wong in 1925, Mok was left destitute, fortunately Dang Sai-king, a better known female student of Wong, organized and paid for Wong's funeral arrangements. Dang and Lam Sai-wing later help Mok and Wong's surviving sons to move to Hong Kong in 1936, where Mok opened a Dit Da Clinic and also reopened the traditional medicine shop Po Chi Lam there. From 1944 to 1969, she served as an assistant instructor to Wong's student Dang Fong and taught Hung Gar to their students at the Wong Fei-hung National Art Society located on Gloucester Road in Hong Kong's Wan Chai area. She would teach at the Wong Fei-hung Physical Fitness Institute until it closed in 1980.
In 1970, she accepted an invitation from a local television studio to film her performing Hung Ga. In 1976, she accepted an interview from Andre Lam of the Real Kung Fu magazine in 1976 to reveal more about Wong Fei-hung's life and herself, and performed Mok Ga for the magazine's photos. Mok died in November 3, 1982, having outlived her spouse by 57 years.
