How to take a bus from Hanoi to Sapa in Vietnam? How much? how long? Thank you~

Just go to Hanoi Railway Station and buy a ticket. It takes about 9 hours. It costs more than 90,300 yuan to sit alone. The sleeping one is more than 200,000 yuan, almost 100 yuan. If you get off the bus, you have to take a van to go up. It's usually between 30 and 40 thousand. I can't remember. They are all private hotels. There seems to be a very luxurious hotel. In fact, you don't have to worry about where to stay, but I think the place is not worthy of its name and not very fun.
