Where can I complain about the smell in the corridor?

If there is odor in the corridor, the property management company should be notified to clean the corridor and find out the source of odor. As stipulated in the property service contract, the property service enterprise shall clean up the public areas within the jurisdiction of the property and remove the domestic garbage generated. If the property is not handled, you can ask the neighborhood Committee for help, and finally you can ask the local urban management or environmental protection bureau for help.
