You can go to Sanjiao Town Labor Bureau (the Triangle Branch of Zhongshan Labor and Social Security Bureau is located in Wan Yue Road, Sanjiao Town, tel: 85409038 85409458), or check the vocational skills training institutions, technical schools or training courses under the Labor Bureau on its website. In such a big city, there must be many such institutions, but it is difficult to distinguish between true and false. It is best to have a training institution directly under the labor bureau, so that what you learn will be more solid. Generally there will be formal operation and theoretical training. The term is usually 3-6 months, calculated according to the class hours. The class hours in different schools will vary according to the examination level. Generally, you will be asked to sign up for the operation certificate and qualification certificate. Don't buy it from a fake witness dealer. I can't find it online. Besides, it is not a real talent, and there is no need to expose it after work.

That's all the basic information. I wish this friend an early study.
