pakistan passport visa procedure. Pls explain how i can get china visa on same same day

If you go to PRC for tourism purpose, you need to apply for a group tourist L type. The first step is to book a tour from a travel agency and then ask the agency to apply for a group tourist L type for you. I’m afraid it’s not likely for you to get it on the same day. As for the details, you should contact with the agency and know about more.
