The reason why Jackie Chan’s son Jaycee Chan is named Fang is because Jackie Chan’s surname is Fang.
In 2004, Jackie Chan publicly announced that he was a descendant of Fang Xuanling, the prime minister of the Tang Dynasty. In the same year, he went to Zibo City, Shandong Province to recognize his ancestor. Jackie Chan's family name is Fang Shilong. He changed his son's name to Fang Zu's name in order to recognize his ancestor and return to the clan.
Jackie Chan's father Fang Daolong went to Hong Kong to make a living in his early years, leaving behind two sons at home. After arriving in Hong Kong, Fang Daolong married another child and gave birth to a son, Chen Gangsheng, who was named Jackie Chan after entering the entertainment industry. Previously, Jackie Chan had always claimed that his ancestral home was Linzi District, Zibo City, Shandong Province, and that he was a descendant of Fang Xuanling. However, the family tree of the Fang family in Fangqiao Village, Shenxiang Town, Jiujiang District, Wuhu City, Anhui Province clearly states: "Daolong was born on December 22, 5th year of the Republic of China when he was ugly. He was hired by the Yin family, had two sons, and became an official. Virtue, second career success, remarriage overseas, unknown year of life, 1st son, stage name Jackie Chan. "Moreover, this family tree was funded by Jackie Chan's father when he returned to his hometown of Anhui in the 1980s.
On August 31, 2013, Jackie Chan came to Wuhu City, Anhui Province to visit his eldest brother. He went to his father's family ancestral hall to check the family tree and recognize his ancestors. Jackie Chan's trip was very low-key.
