Can firefighters who return due to reunion plans still be allowed to enter again?

Yes. According to the official website of the Fire and Rescue Bureau of the Ministry of Emergency Management, it is known that you only need to apply for employment with the leader of your original unit to return to your place of origin, and the National Security Public Security Fire Bureau of your birthplace, and wait for the approval letter from the local Public Security Fire Bureau to apply. Just report to the local police and fire station.
