Aunt 13th is actually just a fictional character in the movie, which has no practical significance.

There is no 13 aunt in history, and its prototype may be Huang Feihong's fourth wife Mo Guilan. Mo Guilan, a native of Guangdong, was born in a martial arts family, and practiced Mojia Boxing, one of the five schools of Nanquan, since childhood.

After 13th Aunt got married, Huang Feihong taught her martial arts and lion dance skills, and Mo Guilan formed the first female lion dance team in the future. After Huang Feihong's death, Mo Guilan moved to Hongkong with Huang Feihong's two sons to make a living. In the future, he successively opened the Huang Feihong Martial Arts Museum and the Mo Guilan Fitness Center, and Hong Kong people happily called her the "Fourth Lady". 1982 died in Hong Kong at the age of 90.
