Generally speaking, to apply for a job in an enterprise, the main things you need to bring are: academic certificate, identity certificate, resume, and proof materials that can prove your ability or qualification, such as: welders need to bring a welder's certificate. Some enterprises also require personal photos (one-inch or two-inch bareheaded photos), and if they have them, they can also bring some supporting materials that can prove their past performance, such as patent certificates and professional title certificates.

If possible, try to know more about the company you are applying for and the job you are applying for. With a confident attitude and decent clothes, the rest is to improvise.
