I want to find a job as a courier in Wuxi, but the courier companies all ask me to change vans (now there are tricycles), but I dare not change because I don’t know how to do it...

This depends on which express company you are looking for, such as SF Express, YTO, STO, EMS, and Huitong. . .

There are also other companies. Some companies do not have a basic salary. They will give you a commission based on the volume of pickups. Some give you a basic salary and then add commissions. Generally, the salary of a pickup worker is 5,000. - Around 6,000, this is the salary of the courier pick-up person here. If you need to inquire about it, it’s OK.
