What specific procedures do I need to go through to go from Harbin to Hong Kong?

You must first prepare your Hong Kong and Macao pass (the document is a must), and it also depends on whether your document is endorsed L or G. If the visa is signed L, you must go with a travel agency. If the visa is G, you can work independently or join a group. If you travel independently, the expenses will be relatively high. Housing in Hong Kong is very expensive, costing more than 5600 yuan. If you go for 23 nights, you must spend 1800 yuan. If you talk to a travel agency, you can stay there for seven days at 1800. And you can go to Hong Kong and Macau, and the room has been booked for you. Food, including tickets and boat tickets to some attractions. If you want to travel on your own, you can find one that allows you two or three days of free activities. You can play by yourself and you don’t have to worry about the room.

This is more cost-effective~ I wish you a happy trip~
