Who is Vision Wei's good friend?

Comparing these two, it should be Jason. Chengdu Division is very United, so Ma Xueyang, Cai Sitao, Jason, Xi Jiachuan, Wang Zhengliang, Zhang Pei, Gao Yang, Xu Mingfei and Roger are all his good friends, and Roger once sang in the promotion competition. In fact, many of the top 50 people in Chengdu are his good friends. The best friend should be Zhang Tao, who later took part in Absolute Singing. They are good friends in the same dormitory, that is, the brothers who sleep in my upper bunk. They auditioned for Happy Boys together. In 50- 10, Zhang Tao, Sugiyama and Vision Wei were in the same group, and Vision Wei advanced.
