In fact, the customer service in the mobile phone is also Ali Vientiane, and the entrance is easy to find.

Log in to Niu Qian first, and then find my application on the workbench page. If Ali Vientiane does not appear here, you can click all the buttons in the upper right corner to find Ali Vientiane in the customer service bar, and then click the Add button at the back to add it to my application for subsequent viewing.
