Stop business for rectification. Zigong LPG filling station has some problems, such as unlicensed operation, inadequate safety inspection before and after filling, and irregular gas unloading management, so it has to be closed down for rectification. Zigong is a city because of salt. The name "Zigong" comes from the famous artesian well and Gongjing, and the place name is named after the well name, so both places call it that.
