One of Vietnam's two famous French-style mountain towns, there is Sapanan in the north. You can cross the Yunnan River to the old street by minibus to Sapa Town. Hanoi can take the sleeper bus for six hours or the train to the old street and then turn. If there is enough time, it is recommended to take the train, especially if you don't have money, you can book the Victoria Hotel, they have a special train. I only stayed for one day this time, going to Cat Village to hike and do the cable car to Pansibang Peak, the highest point in Indochina. There are also many foods in the town, and the price will feel very cheap for the Chinese. A great trip, but unfortunately the gods are not beautiful.
