—synopsis—

Gong Baosen, president of the Chinese samurai club and head of the Eight Diagrams Xingyi Gate, came to Foshan, Guangdong Province from the north to hold a retirement ceremony. Ma San, his first disciple, injured a Foshan martial artist at the banquet, so that the local martial arts community recommended Ye Wen, a master of wing chun, to play in Gong Baosen. After IP Man won, Gong Ruomei, the daughter of Gong Baosen, immediately challenged IP Man and won back a battle.

The Japanese invasion of China broke out. On the way to study medicine at the university, Gong Ruomei helped the Japanese to get rid of the Japanese on the train. At this time, Ma San turned traitor to Japan, turned against Gong Baosen and killed him. Gong Ruomei put off her marriage for revenge, became a Taoist, and vowed never to marry or apprentice for life, in order to fight Ma San in a decisive battle, and eventually won, but at the same time suffered serious internal injuries.

After the war, many martial arts practitioners moved to Hong Kong. Ip Man also arrived in Kupang in 1950 and began to teach Wing Chun. Later, he was reunited with Gong Ruomei, who was practicing medicine in Hong Kong. Later, Yixiantian also went into exile in Hong Kong, opened a barber shop and taught octupole boxing in Hong Kong.

Gong Ruomei didn't accept apprentices and spread art according to her oath, but Ip Man carried forward Wing Chun.
