The story of Yang Zhi selling knives in Water Margin, 100 words.

Yang Zhi came to Tokyo to make up for the service of the temple administration, but Gao Qiu got in the way and failed to do so. Because of all the travelling expenses, he reluctantly sold the treasure knife left by his ancestors, changed some travelling expenses and threw it elsewhere.

However, it happened that the scoundrel Niu Er, who had a bad hair blade, made things difficult again and again, cutting copper coins with a knife and pulling out his own hair for experiments.

He also unreasonably asked Yang Zhi to try chopping people. Yang Zhi said that he would chop down a dog, but Niu Er refused, and insisted that Yang Zhi carry it for nothing.

Yang Zhi was very angry. They fought and killed Niu Er. After killing Niu Er, Yang Zhi asked his neighbors to testify. I went to Kaifeng to turn myself in, but I was confiscated. Bao Dao didn't go to the government.

Extended data:

Yang Zhi, the grandson of Yang Gong of three generations and five generations, was called a green-faced beast because of a large bruise on his face. He lived in Kansai since childhood and was employed as a martial arts official in his early years.

After escorting Hua Shigang, he capsized in the Yellow River and dared not go back to Beijing to die, so he had to take refuge in the Jianghu. After leaving the Snow Mountain Temple, Lin defected to Liangshan, where he was made difficult by Wang Lun, the owner of the stockade, and had to go down the mountain to find warlords.

Yang Zhi is on the verge of forgiveness. He wants to go to Tokyo to seek reinstatement. He happened to pass by the water margin and met Lin Chong. The two men fought more than fifty times, regardless of the outcome, and were finally persuaded by Wang Lun.

Wang Lun intended to recruit Yang Zhi to join the partnership, but Yang Zhi declined politely, so he had to go. After Yang Zhi went to Daming Mansion, he was appreciated by Liang Zhongshu who stayed in Beijing, and was left in the mansion to listen to politics.

Seeing that he worked hard, Liang Zhongshu wanted to promote him to the rank of deputy in the army, but he was worried that someone would refuse to accept him, so he arranged for Dongguomen to teach martial arts. Yang Zhi defeated Zhou Jin, the deputy army, with a gun and an arrow.

Liang Zhongshu asked Yang Zhi to replace Zhou Jin as the deputy army, but this annoyed the real army Suochao. Suo Chao fought against Yang Zhi for more than fifty times, regardless of victory or defeat.
