The reason why Jackie Chan’s son is named Fang Zuming:
“Jackie Chan” is the stage name, not Jackie Chan’s real name;
Jackie Chan’s father’s surname is Fang, and his name is Fang Dao Dragon, so Jackie Chan’s real name is Fang, and he is called Fang Shilong;
So the name Fang Zu should follow the ancestral surname "Fang", so there is no problem with the surname Fang and the name Fang Zu.
Jackie Chan was born on April 7, 1954 in the Central and Western District of Hong Kong. His ancestral home is Wuhu, Anhui Province. He is an actor, director, action director, producer, screenwriter, and singer in Hong Kong, China.
Jackie Chan is a well-known martial arts superstar in China and even around the world. The name Jackie Chan is just his stage name, which is why he and his son have different surnames. Jaycee Chan is the son of Jackie Chan and Hong Kong star Lin Fengjiao;
Jackie Chan's father Fang Daolong was born in Jiujiang District, Wuhu City, Anhui Province. Before meeting Jackie Chan's mother, Fang Daolong had already given birth to two sons, Fang Shide and Fang Shisheng, with his first wife. In 1947, Fang Daolong changed his name to Chen Zhiping after arriving in Hong Kong and married Jackie Chan's mother. On February 28, 2002, Jackie Chan's mother died of illness in Canberra, Australia. On February 26, 2008, Fang Daolong passed away in Hong Kong.
