洪拳
In his younger days, Wong earned a living by performing martial arts and acrobatics in the streets. One day, he encountered Luk Ah-choi (陸阿采; Lu A'cai), a notable practitioner of the martial art Hung Ga. Luk was also a student of Reverend Jee-sin, one of the legendary Five Elders who survived the destruction of Shaolin Monastery by the Qing government in the 17th or 18th century. Luk saw great potential in the young Wong, accepted him as an apprentice, and taught him martial arts. Another legend, which reflects historicity in the Hung Ga lineage, says that Wong learnt martial arts from his father, Wong Chun-kong (黃鎮江; ca. 1782–1867), also named as Wong Tai (黃泰), who was taught by Luk Ah-choi.
