Does the gas company know the arrears if it doesn't sign the agreement?

I see. Whether you owe money or not has nothing to do with the agreement. Natural gas companies know whether each user is in arrears through meter reading records and user payment. China Gas is one of the largest cross-regional comprehensive energy service providers in China, and it is listed on the main board of Hong Kong Stock Exchange. It is the only local natural gas company that China Gas has the right to exploit in China.
