Lanzhou Ramen is cheap at 6 yuan a bowl, and the rice set meal at around 10 yuan is slightly better. If you want to eat a lot of dishes, you can do the math yourself. For seafood, at least dozens.

2. You asked about air tickets, and they didn’t tell you where you were. How can I tell you? I’m from Henan, and I usually charge less than 600-700 when I come to Zhengzhou.

3. The best attributes Yalong Bay, but there is a charge for swimming there; Dadonghai is free and fun, a must-go place with many people, swimming and boating; Sanya Bay is close to the urban area, where you can feel the integration of the sea and the city.

4. There are many sea view rooms. Yalong Bay is a cluster of star hotels, and other places are not very expensive.

5. A T-shirt is enough for the upper body. It's a good idea to bring a light shirt just in case.

Have a nice day!
