In order to ensure the health and safety of passengers, Chongqing Communications Investment Rail Group has upgraded the "Yuchangxing" APP since September 6, and the "ride code" and "Yukangxing" are combined into one, and the "Yukangxing" code is automatically verified before the "ride code" is generated. When citizens take the rail transit, they only need to open the "Yuchangxing" APP and display the "boarding code".
Instructions for use 1. If the status of "Yukon Code" is normal (green code), the "boarding code" is displayed normally and displayed in green;
2. If the status of "Yukon Code" is abnormal (yellow code or red code), the "boarding code" will not be displayed and an abnormal situation will be prompted.
Chongqing Rail Group reminds that users who have not opened the "Yu Kang Code" will automatically jump to the "Yu Kang Code" application page after opening the "Yu Changxing" app, and then use the "Yu Changxing" ride function after the application is successful.
