As for the hepatitis B test upstairs, I can't help it, because all the salespeople in Oceanwide live together and cook by themselves. If there are infectious diseases such as hepatitis B, it is easy for colleagues to get sick.
The probation period seems to be around 1500, and the commission is 4%. In fact, entering Ocean King will brainwash you and instill in you the concept of its sales and service. If you can't accept it, then give up. If you can't accept it, you can't work in the company.
