How to get a group tour L visa to Hong Kong through Shenzhen North Station?

The L-sign team must go through the customs in the name of a tour group and go through the formalities of sending a tour group to the travel agency. In this way, you have a customs clearance list, and you can go to the customs for border inspection yourself. When you come back, you don't have to join the group. You can come back alone. It is suggested that you can take Huatong bus to downtown Hong Kong and take Wenjindu Port, which is very fast. Hope to adopt.
