If the travel itinerary code appears in a place you haven't been to, it is recommended to check whether the location is at the junction of the two places. Because the communication big data travel itinerary service uses base station data, the base station signal at the junction of urban administrative divisions may cross over the places you have never actually been, but because of the junction of the two places, you will receive the roaming signal of the base station here, resulting in the deviation of the query results; If there is no such situation, it is suggested that the manual customer service provide information such as the city displayed on travel itinerary for feedback processing.
