Did anyone use Youlan.com to find a job?

It's a job search website, which specializes in finding jobs for blue-collar workers. Not an intermediary. They have stores or branches offline. When applying online, you can meet them and send them directly to the enterprise, or you can go directly to the enterprise without charge.

Precautions:

Prevent stealing personal information in the name of recruitment. Be careful when the other party asks you to provide strange proof materials. Under no circumstances can you disclose any personal information of yourself to a "recruiting unit" with only a little knowledge. Once you find any signs of infringement, you should report it immediately.
