What do you mean, go back to the mainland?

At home, return to the mainland from the periphery. The word "inland" is a vague definition and has different meanings on different occasions. The context is "inland areas of the same country", that is, "domestic areas". Returning to the mainland means: returning to the mainland from the periphery of the country. There are two ways to return to the mainland by land. One is to enter the country through Shenzhen Bay Port, and it is necessary to reserve the quota of Shenzhen Health Station in advance. The second is to take the Zhuhai shuttle bus (also known as Kimba), and you also need to make an online reservation. Tickets are on sale at 8 pm every Tuesday this week.
