I am Abdul Saheem. I plan to travel to China on business and my wife will accompany me as well.

Hey, you need to apply for a M type because you have a business trip. have you gotten your M type? If you plan to ask your wife to accompany you, you can just help her acquire a L type. Your buying agent can send your wife an invitation letter. Then you wife needn't provide hotel reservation and round-trip air tickets.
