Okay. Longyu Gas Station in Shuangcheng is a relatively famous one. The biggest feature is that if you come here to refuel, you can get a free car wash for life. You get points for recharging your card and refueling, and the service and price are particularly good, especially at the Shuangcheng Longyu Gas Station Petroleum Terminal located at the intersection of Xiuhuacheng Road and Tongda South Road in Luozhuang District.
