Dongxing City in Guangxi, a small town on the China-Vietnam border, just opened a high-speed rail at the end of last year. The flow of return trips to Vietnam to visit relatives and the flow of Vietnamese students returning to school during the beginning of the semester are superimposed.

The China Railway 12306 APP system shows that all tickets for the whole day have been sold out. Recently, a large number of Chinese and foreign passengers have queued up at Dongxing Station, waiting to enter the station.
