Charbel, you need to prepare passport and its photocopy, the completed application form, a recently-taken passport-style photo, an invitation letter from a Chinese travel agency, round trip air tickets and hotel booking record, financial support proof and work certificate. Generally speaking, it is better to make the application in your home country. I’m afraid the invitation is necessary.
