Then I came up with a plan to do private work, which has not been used (but some students are using it) for your reference:
Find a well-known trading company, find a well-known trading company salesman (must be well-known) and sign a trade agency contract with them privately. After that, you contact customers in your own name, but do business in the name of their company. They do business, industry and commerce, taxation and so on. You are responsible for finding factories, customers and so on. They want performance. If you have a single customer, they will be willing to cooperate with you.
Prerequisite: 1, there must be a single customer; 2. This trading company and this salesman must be familiar with you, and it is best to have a personal relationship; I don't need to say anything confidential.
