Is Wei Sicheng a half-blood?

According to this person's personal profile, I know this person is not a half-blood.

Wei Sicheng is a wrist wrestler in China. It is a high-value god in the wrist force circle. Won the Japanese player's 70 kg class, and was called "the king of 70kg right-hand man". He is very popular and powerful in the wrist circle, but Wei Sicheng's strength has been questioned by Korean wrist representatives before.

This person won the national wrist wrestling championship in 2020, the 70kg right-hand champion in the Chinese wrist wrestling competition on 20 18, and the 70kg right-hand champion in the Chinese and Korean wrist wrestling competition on 20 18.
