Qinhuangdao citizens can't use Beijing Health Treasure.

According to the relevant information, the query shows that it can be used, which has nothing to do with your household registration. As long as people who come to Beijing, travel to and from Tianjin and Hebei in this city, after coming to Beijing (returning to Beijing), they can verify the trip record of Beijing-Tianjin-Hebei through "Beijing Health Treasure" and apply for "no abnormal" health status.
