Ask the property company to issue a water and electricity bill to prove that the other party will charge legally?

Literally, it is illegal, and the law stipulates that taxes should be paid.

However, the actual users of public utilities are tap water producers and power plants.

The property is at most a collection, unless the price he charges is higher, then the price increase should be counted as a service fee, and according to the regulations, an invoice should be issued.

But this part of the invoice amount is not actually your utility bill.
