Hello, I want to ask about the invitation letter for travel.

If he is traveling in China, you can ask the local international travel agency to send an invitation letter for you. You need to provide your passport number (preferably a copy of your passport), list, gender, age, purpose of coming to China, date of coming to China, date of departure, destination, hotel, reception (party),

Only international travel agencies have the right to apply to the Tourism Bureau to send invitations to China people, but ordinary travel agencies cannot.

Travel agencies charge a certain fee.
