On Alibaba, there are indeed some companies that do manual processing, but there are also some informal companies.

Here are some ways and suggestions to distinguish:

1. Observe the type of company: Some companies named "XX Business" or "XX Trade", especially those without production lines and factories, need to be particularly careful. The cost of such companies is relatively low, and they may cooperate with processing factories instead of directly producing.

2. On-site inspection: If possible, it is recommended to visit these companies in person to see their actual operations. Some companies may refuse customers to visit them, or only display luxurious decoration in the office building to show their strength.

3. Understand the cost: Some companies may require first-time customers to pay material fees before taking the goods, or require a contract to be signed. In this case, customers should read the terms of the contract carefully and make sure they understand all the details.

4. Understand the workers: If the manual work is sent out from a nearby factory, most of them are reliable. Because the current labor wages are about 3,000 yuan, the factory is also responsible for the workers' food, accommodation, management, insurance, etc., and sometimes it is restricted by the production location, the cost is very high.

5. Be cautious about online promotion: Some manual processing scammers will pay to buy the TrustPass on Alibaba, and then publish a lot of manual processing information. On some search platforms, they can get promotion and attract more people.

In short, there are both real and fake manual processing on Alibaba. Customers should pay more attention when choosing, conduct detailed investigation and understanding, to ensure that their rights and interests are not harmed.
