May Day travel, from Pingxiang, Guangxi to Puzhai. Do you need to go through any formalities? How many ways to get it?

There is no need to go through any formalities. Puzhai is only the logistics commodity market of the two countries, which belongs to China. You must bring your ID card. I don't necessarily check my ID card, but sometimes the armed police will. Friendship Pass is good, and you can climb the mountain (you must climb it, the mountain is steep, and there is a fort on the top of it overlooking Vietnam) ... Don't talk to the people in the travel agency, who are bluffing. Have a nice holiday!
