The title of reserve cadres, which is empty in name, is to ask you to do odd jobs:

If you don't have a fixed position, you can do anything and anyone can order you around;

The salary is the lowest level, and the welfare basically has nothing to do with you.

People with no background will become full-fledged workers in the foreseeable future.

after reserving you for a few months, you said that you were unqualified and were willing to be kicked off by them.
