As for what is said upstairs, I think I have a say:
If the average salesman only works for two months, most of them choose to leave because of poor performance.
The company leader is fine. I don't know who's up there. Personally, I don't think this phenomenon exists (since 10 joined the company, no leaders have been found on it).
Some colleagues in the company were introduced. I don't know what high quality means, but I feel that my colleagues get along well and are very happy.
