According to the regulations of the Education Bureau, the certificate of self-healing of the common cold needs to be opened in the hospital, usually in the respiratory department of the hospital. The doctor confirms that you have recovered through examination, and issues a certificate, with a test sheet and a nucleic acid test report.
The certificate of resumption of schooling varies according to the regulations of local schools. Take Guilin as an example: students usually take a semester off for one academic year. After the expiration of the suspension period, students who have suspended from school must hold a health certificate issued by the county-level medical unit or the relevant unit at the county level.
