2. Group purchase: You can buy Tongan hot springs or Tianmu hot springs.
3. Accommodation: If you are young enough, go to a family hotel. There are many family hotels in Zeng Cuo An Village village, and they are on the island road. Petty bourgeoisie can watch the sunrise and sunset. Book in advance. May Day may be very popular. I know that Tomb-Sweeping Day Guo Cheng Family Hotel is full, and it has just been renovated recently, which is not bad. The price is 120- 160, and you can search for group purchase.
P.S. had better go to Gulangyu later. There are too many people coming in and out.
