How to distinguish the proprietary part of the owner from the public part of the property that should be managed?

Self-use parts include: doors, windows, indoor ceilings, interior walls, floors, non-load-bearing partitions, self-use balconies and other indoor decoration; Self-use equipment includes: household meters, electrical appliances and pipes in water meters (including household meters), household water meters and gate valves or switches in front of water meters, sanitary appliances and related sewer pipes. The owner shall be responsible for and bear the responsibility and expenses for repairing and updating the components and equipment for his own use. If the toilet, kitchen and sewer pipes of the superstructure leak water to the lower floor, the owner of the superstructure shall be responsible for repairing it.

* * * Usage parts include: roof, external wall, stairwell, corridor, public hall, equipment floor, courtyard wall, etc. * * * Equipment and facilities include: equipment and lines from the front switch of the household meter to the master meter, water supply pipes and accessories from the gate valve of the household meter to the master meter, main sewage pipes, rainwater pipes, garbage tanks, flue (exhaust duct), mailbox main body, lightning protection facilities and TV antenna. * * * The maintenance and updating responsibilities of the parts, equipment and facilities used by * * * shall be borne by the relevant owners who use * * *, and the expenses shall be shared by the relevant owners who use * * * according to their share of the building construction area, and shall be paid from the special maintenance fund, and the insufficient part shall be paid by the owners.

In fact, it is also very easy to distinguish, such as water pipes or switches, to see if it is your home, yes! It is a self-use part because its opening and closing has nothing to do with others. If not, it depends on who uses it. If more than one * * * is used, like the main switch of the unit where you live, there is no electricity when it is turned on. There is no doubt that this switch is common to this device. If there are two * * * *, such as some floors upstairs and downstairs, they are called adjacent parts according to laws and regulations, and the floors are broken by adjacent parties.

We can't simply think that the indoor part is for personal use and the outdoor part is public, otherwise the air-conditioning host hanging outdoors will be inexplicably public.
