The traffic in Hanoi is chaotic, but the public security feels good. I took a taxi outside several times after 0/2 o'clock in the evening/kloc-it's okay. And I haven't heard of fighting, killing and setting fire for so long.
There are many foreigners in Hanoi. When you stroll in the Restoration Sword Lake at night, you will find many languages (English, Chinese, Korean, Japanese, etc. It's a romantic place, and there are many Vietnamese couples snuggling on stone benches by the lake, which is a harmonious scene, so the Vietnamese are not exclusive.
Of course, most foreigners come from China. When you walk in the street, you sometimes hear Mandarin. It can be said that the older generation of Vietnamese still have a good impression on China, and many of them can speak Chinese. However, in recent years, too many people from China have gone there, and some people's actions have tarnished the reputation of China people there. A Vietnamese girl once told me that foreigners in Vietnam, China people are the least welcome, but of course it is only relative. The vast majority of China people are still very good in Vietnam. In fact, I have been there for so long, and I don't think they are unfriendly to me.
Young people in Vietnam, in particular, are very open-minded and enthusiastic. I got lost when I first went there, and some young Vietnamese helped me find my friend. Later, I met some college students there and often took me to drink coffee by motorcycle. The young couple in that coffee shop also learned Chinese.
It's actually quite simple. If you are friendly to others, others will be friendly to you. In the folk, generally speaking, political color is not considered.
