The date on Qinhuangdao Health Treasure Travel Card

14 days. Travel code users' travel calculation in the first 14 days is done in the background of operators, and the statistical rule is that statistics will not be recorded until they stay in the local area for more than four hours, because operators usually count data in the middle of the night. So 14-day trip refers to all cities that have stayed in 14 days from the day before I display or check the trip code, and places that have been before 14 days will generally update the trip code during the day of 15.
