The weather in Sanya in January.

Swimming is ok in this weather. As long as it is sunny, Sanya will be very hot. Bring a shirt to your child when it is cold in the morning and evening, and be sure to bring sunscreen. Children should pay attention to sun protection when swimming, and bring hotel bath towels or bathrobes when swimming, which can be worn after swimming. If you are an adult, you can wear short-sleeved shorts and slippers. I feel that there is nothing more convenient than wearing slippers in Sanya.

Yalong Bay is a little far from the urban area, so you can take bus 15 and tourist shuttle bus to the urban area. Almost all the four-star and five-star hotels around Yalong Bay are expensive to eat, and there is an extra service charge of 15%. You can buy seafood in the first market and then find a seafood processing shop nearby for processing. The processing fee is 5 yuan a catty, and you can also book a day trip and other entertainment items on Taobao, which is much more cost-effective than booking in local hotels or outlets.

Don't pay attention to tricycles that solicit customers at random by the sea and people who send business cards to solicit customers for dinner on the road. Don't buy fruit carried by the roadside. Those who are brought up by Mrs. Li to sell pearl necklaces should be rejected directly.

In addition, prepare some medicines for diarrhea and Jianwei Xiaoshi tablets. Children should eat less seafood because it is not easy to digest. Have fun!
