ok Bo-Chuen (Huo Baoquan) learned his wing chun kuen from Wong Wah-Bo and Painted Face Kam in the city of Foshan where he served as a ngao moon bo tao (Imperial constable) during the end of the Ching dynasty. Fok was renowned for his remarkable depth of martial knowledge, his wing chun kuen skill, and especially his talent with blades, which earned him the nickname Seung Do Fok (Shuang Do Huo, Double Knife Fok).

In the early 1900s, Fok Bo-Chuen was hired by the owner of the fireworks store on Zhenbai road to teach his sons, Yuen Chai-Wan and Yuen Kay-San, the skills of wing chun kuen.

ung Siu-Ching (Feng Shaoqing) was a native of Shunde, Guangdong. At a young age he moved to Guangzhou where he apprenticed at the Dragon & Phoenix Embroidery shop that, among other things, made costumes for the Red Junk members. Fung proved ill-suited for a life as a embroiderer but, fortunately, a chance encounter with Painted Face Kam led to him being taken as the opera performer's student.

Fung remained on the Red Junks until he was an adult, and thereafter traveled the region, taught some students, and eventually began work as a body-guard (reportedly for the Governor of Sichuan province), and later an Imperial Marshal in Guangdong.

When he was just over 70 years of age Fung retired to the Yuen Family Estate located on Songyuan Dajie (Mulberry Gardens Mainstreet) in Foshan, and taught the martial arts to Yuen Kay-San and his elder brother Yuen Chai-Wan. Studying alongside them were Ma Jung-Yiu, Ngao Shi (the grand-teacher of Cheung Bo) and others.

Fung Siu-Ching lived, taught, and was cared for at the Yuen family estate until he passed away at the age of 73. Yuen Kay-San and his classmates officiated at the old marshal's funeral.
