What if it is destroyed by neighbors twice in a row?

If I guess correctly, the heating in your building is an old-fashioned system, and each unit has a master valve, which cannot be controlled independently. The other party thinks the room is too hot and has to turn off the main valve. Best policy: I suggest you complain to the property and ask them to install a protective device with a lock outside the valve. At the same time, install a thermometer at home. If the indoor temperature is lower than the promised temperature, you can take photos or videos as the basis for refusing to pay the property fee and heating fee. The bottom plan: install metal protective shell at your own expense and lock the valve. Follow the post "Who closes the valve and who cares about the glass?" The next policy is to sue all residents and properties in this unit, and ask all residents in this unit to find out the responsible person and ask them to bear the function fee, cold medicine fee, mental damage compensation, lost time fee and prosecution fee. If no one gives orders or surrenders, all residents in this unit will bear the loss of the above expenses.
