What unit does the vegetable market administrator belong to?

They are all contracted by private enterprises, not units, but ordinary property companies or management companies. In the past, the vegetable market was directly operated by urban institutions, but now it is basically a private enterprise with contract system.

The manager of the vegetable market is just an ordinary part-time job, not a leader. You should know that a leader is a person who works for the welfare of the people and leads them to happiness.
