ZmjjKK

Zmjj is the in-game ID of Kangkang's older brother, Zheng Mingjia. Kangkang’s full name is Zheng Yongkang, and his game ID is KK康康 (Kangkang). Out of gratitude for his brother’s unwavering support, Kangkang decided to include part of his brother’s ID in his own, creating the name ZmjjKK you see today. This way, his brother’s influence could be recognized around the world.
