Today I went to Huizhou to apply for a job as a computer apprentice. No food or accommodation was included, and there was no salary. Are all computer apprentices like this?

Yes, all computer apprentices are paid, but it is generally relatively low. If you are looking for an ordinary apprenticeship like typing, making forms, etc., the apprenticeship salary should be around 800. , if you are looking for a professional computer apprenticeship such as engineering drawing, then the apprentice salary is probably lower, but I think it is at least one or two hundred. As for food and lodging included, that's definitely available, unless you don't need it. In addition, unless you have just graduated from high school or junior high school, and your home is in Huizhou, if this computer apprenticeship is introduced by a relative of your family, the situation you mentioned is still possible.
