There are three theories about who Wei Yang's teacher is: the first is Uncle Cuo; The second statement is guiguzi; The third argument is Shijiao.

Shang Yang was a statesman, reformer, thinker and representative figure of legalism in the Warring States period. He was born in a declining aristocratic family in Weiguo, and is a descendant of the King of Weiguo, also known as Wei Yang. Later, after Shang Yang came to Qin State, he took Shang as his name.

However, after the political reform, Shang Yang was framed for rebellion and began to flee, but no one wanted to take Shang Yang in. There is no way. After Shang Yang returned to Qin, he was forced to sneak back to the feudal city merchants and launch city soldiers to attack Zheng County. So Qin Huiwen sent troops to attack, and as a result, Shang Yang failed and died, and Shang Yang's family was wiped out.

The first uncle CuO, known as Shang Yang's teacher, was the prime minister of Wei. Many people say that Shang Yang studied with his uncle in his early years, appreciated his talent and gave him a lot. Later, Shang Yang learned something, and when he heard of recruiting talents and scholars, he went to the State of Qin with the Fa Jing.

Shi Jiao, the second teacher of Shang Yang, was honored as a corpse driver. He is one of hundred schools of thought in pre-Qin Dynasty and one of the outstanding representatives of ideology and culture in pre-Qin and Sanjin Dynasties. His life has made great contributions to social reform and philosophical thinking. He made suggestions during Shang Yang's political reform.

The third Guiguzi, known as the teacher of Shang Yang, is a mysterious legend in the history of China. His intelligence is extraordinary. According to legend, the four meat moles on his forehead became haunted houses, which were highly respected by everyone and made great contributions in the history of China. In addition, many disciples of Guiguzi have made very high achievements, so many people think that Shang Yang's teacher is Guiguzi.
