Can the rechargeable electric card and water card of residential property be recharged at China power grid and tap water charging office?

No, because the identification chip of each card is set differently, the power and water companies can't pay the utilities separately. Even if they can pay, they won't accept it, because the power bureau and the water company usually sign a collection and payment agreement with the property, depending on whether your electricity and water are directly imported by the power bureau and the water company. If you need secondary power supply or water supply, the price is different, so you can't pay the electricity and water company, and we will pay the electricity bill.
