Yue Fei was a famous anti-gold star in Song Dynasty, and his heroic deeds were widely circulated, especially the story of "stabbing her mother-in-law".

There are several legends about the story of "mother-in-law tattoo".

Some said that Yue Fei was fighting in the front line and his father died of illness. Yue Fei came back to be filial to his father. After burying his father, Yue Fei saw his mother alone at home and didn't want to go back to the front. He wants to be filial to his mother at home.

Mother-in-law is a person with a deep understanding of righteousness, thinking that she can't miss the country to recover lost ground just because she is small. In order to inspire Yue Fei's patriotic enthusiasm, she tattooed the words "faithfully serve the country" on her back, reminding Yue Fei to fight bravely and faithfully serve the country.

It was also said that Yue Fei could not beat him because of his superb martial arts, and he wanted to buy him off, give him higher treatment than in Song Dynasty and ask him to surrender. At that time, Yue Fei was too young to make a decision and discussed it with her mother.

Of course, my mother wouldn't agree, and she was afraid that Yue Fei would move away, so she tattooed the word "loyal to the country" on Yue Fei's back, reminding Yue Fei to be loyal to the country, to do his duty faithfully, and to be sworn to the enemy, which also showed Yue's loyalty to Dasong.
