Lao Gao is keen on clash royale, and he is also an anchor. Earlier, there was a game competition in Taiwan Province Province, and Lao Gao went to Taiwan Province Province to give a live explanation.

KUAIZERO originally seemed to be Lao Gao and another anchor Lao Rou jointly trying to push the channel, but later it was shelved for some reason and turned into a talk show between Lao Gao and his sister-in-law.
