Dongxing National Gate Scenic Area is located at the southwestern end of the coastline of mainland China, bordering the Beibu Gulf in the southeast. It is the most convenient port city for Guangxi and Southwest China to Southeast Asia, and is also one of the famous overseas Chinese hometowns in Guangxi. The scenic area was built in the Ming Dynasty and flourished in the Qing Dynasty. It has a history of more than 400 years. It integrates cross-border tours, shopping tours, sightseeing tours, etc. It is an important distribution center for Chinese and Vietnamese tourists. Dongxing, the southwestern border, is the place I look forward to most on this trip to Guangxi. I have always wanted to check in at various border gates. This is the closest place to Vietnam.
