Refers to JJKing.

Devil Bo just comes from the anime "The Adventures of Jackie Chan". He is one of the eight evil villains - the Mountain Demon. He has a very ugly appearance, with obesity and short limbs.

Fans of League of Legends anchor JJ King (Gangzi) discovered that the two looked similar (mainly fat), so they called JJKing the devil Bo Gang, especially when he was angry with his teammates while playing games. When someone breaks the defense and curses someone, water friends will flood the screen with: "Devil Wave has just transformed!"

Anchor introduction:

JJKing, a contracted anchor on the Douyu live broadcast platform, broadcasts "Heroes" Alliance" game, game ID: douyu丶jjking, is a Sword Queen unique skill player, known as the "Sword Queen Godfather".

In the 2021 China-Japan-Korea competition, JJKing’s Sword Lady gave the Korean anchor team a huge headache. After that, although the Korean anchor team kept banning JJKing's Jian Ji, JJ King still relied on Qinggangying to perform as well as Jian Ji.
