Both are state-owned gas stations, which one is better, Sinopec or PetroChina?

The only state-owned gas stations in my country are PetroChina, Sinopec, CNOOC and Sinochem. There are very few CNOOC and Sinochem gas stations, usually PetroChina and Sinopec. The difference between state-owned gas stations such as PetroChina and Sinopec and private gas stations can be distinguished by the following methods: First of all, look at the name of the gas station. PetroChina and Sinopec will appear on the eaves of the gas station canopy. Yes; secondly, most PetroChina and Sinopec have convenience stores. PetroChina calls it Kunlun Hospitality, and Sinopec calls it Yijie; thirdly, most PetroChina and Sinopec gas stations now allow you to swipe your own IC card; and there are CNPC employees wearing Yellow overalls, Sinopec employees wear blue overalls.

The source of the oil in private gas stations. In fact, the quality of the oil in private gas stations is also guaranteed, because part of their oil comes from three barrels of oil, and they will buy locally refined oil, three barrels of oil. We used to buy locally refined oil, but now the three barrels of oil have their own refineries, so there will be a surplus of locally refined oil, which will then be supplied to private gas stations, so there is no problem with the oil quality.

Private gas stations are not as well-staffed as Three Barrel Oil. They only need a few refuelers, and their salaries are not very high, and they do not require formal accounting. Find an accounting company to report your tax status.
