DOTA2 is a well-known team game, which was produced by Korean game companies and introduced to China. Among them, csdx refers to making a hullabaloo about and attacking players directly. At first, it was the fifth member and other members used by Brother Chicken to scold 4 1yy, but now it is specifically referred to Brother Chicken and all people who like Brother Chicken by water friends.

DOTA, translated as the Knife Tower, is a customized map based on warcraft 3: Frozen Throne and an RPG map officially recognized by Blizzard.
