When Hong Kong is an anti-epidemic volunteer, just go directly to the volunteer group.

You also need to apply for a pass to and from Hong Kong and Macao. You must bring your household registration book and the original ID card to the exit-entry administration where your household registration is located. You can stay in Hong Kong for seven days. After you get it, you can enter Hong Kong from several ports in Shenzhen, including Huanggang Port (24-hour bus clearance), Luohu Port (next to Luohu Railway Station, you can enter Hong Kong by subway), Shenzhen Bay Port (bus) and Shekou Port (ferry).
