The Gas Bureau said: Because of supporting environmental protection, electronic bills are now provided, and the gas bill is issued once a month, and the electronic bill will be sent around the 5th of the following month (generating the gas bill of the current month, that is, the gas bill from the middle of last month to the middle of the current month), but it has nothing to do with the bill immediately after the gas is recharged.
