How about looking for a job in Wuhan market? Is the above information true? Should I send my resume or call the number left on it directly?

The above information is generally true, but you also need to have some resolution, because the possibility of cheating is not ruled out. You can send your resume first, and if you are suitable for their position, someone will naturally call you. As for making a phone call, it is also possible. You can test each other's sincerity by asking questions. If they are sincere, they will make an appointment for you to go to the company for an interview. You can know whether this is true or not by the tone of the other person. If the other person says something on the phone that has nothing to do with work, or asks you to go somewhere else, it's best not to go.
