Vietnamese restaurants cannot be opened everywhere. It is best to open it in a place where Vietnamese people are concentrated. For example, near Daxue Road in Nanning, Guangxi, near the border of the pass is better. If you want to run a Vietnamese restaurant, you can't run it according to Vietnamese standards, because China people will think it is unsanitary. You should use China's standards to create Vietnamese characteristics. The price depends on the scale and grade of your investment. If you do it in Guangxi, it will cost 40,000 to 50,000 yuan.
