What about Shenzhen Rihai Communication Technology Co., Ltd.?

Shenzhen Rihai Communication Technology Co., Ltd. is rubbish, and they like to play abnormal games. Take recruitment as an example. Guanlan Changgong has a big banner, which says to recruit a large number of general workers. I remember there were more than 200 applicants at that time, and they called a dozen people in, and then they said no, they were not psychopaths. What are they?
