Where can I get half of the gas stamps? Is the stub still usable?

This ticket can be obtained at gas stations, but cannot be used.

All gas stations can issue fuel invoices. Whether it is PetroChina or Sinopec, there is an app, or you can scan WeChat directly. After refueling at any outlet, the fuel invoice will be sent directly to your mobile phone and returned to your work or print shop. Just print directly.

If the invoice is incomplete and cannot be used as an accounting voucher, you can negotiate with the other party to have the supplier issue a new one.
