Is it necessary to go through the hospital before making a phone call to complain about the property management of the hospital 12345?

Yes 12345 is the service hotline of the national government. The government service hotline 12345 will inform the relevant personnel of the hospital to investigate and understand after receiving the complaint, and the hospital will handle it. After the hospital handles the case, it needs to be fed back to the government service hotline 12345, and then the government service hotline will pay a return visit to see if the complainant is satisfied with the handling result of the hospital. Therefore, it must be handled by the hospital first.
