Should Shenzhen go back to Tianmen for isolation at its own expense?

No need. Shenzhen, referred to as Pengcheng for short, is a prefecture-level city under the jurisdiction of Guangdong Province. It is a sub-provincial city in Guangdong Province, a city with separate plans and a megacity. Tianmen is a county-level city directly under the jurisdiction of Hubei Province, and it is a member of Wuhan city circle and the middle reaches of the Yangtze River. According to the announcement issued by the local epidemic prevention and control center, because the money spent on quarantine during the epidemic period is paid in advance by family members, there is no need to pay at their own expense. The living environment and special food in these two areas are very good.
