1. ID card or household register, air tickets, Sanya travel guide, itinerary and other information. ?

2. Credit card, change and cash.

3. Mobile phones (don’t forget to pay before leaving), cameras and other chargers, and remember to bring some large-capacity memory cards.

4. Change of clothes (the temperature difference between day and night is large, long sleeves are a must). When you arrive in Sanya, you must go to the sea. You must prepare a swimsuit, swimming goggles, earplugs, and beach slippers (personal recommendation: garden clogs, practical!). Bring all your colorful clothes, and you will know that the bright colors among the white clouds, blue sky, clear sky and blue sea are the most important factors in the beautiful moment.

5. Carry-on pocket: put your ID card, cash, room card and credit card in it and carry it with you to prevent loss or theft. Don’t carry too much cash with you (you can store it in the hotel safe or lobby). ?

6. Paper and pen can record something.

7. Medicines: mosquito repellent, anti-allergic medicine, antidiarrheal medicine, cold medicine, analgesic medicine, Bondi and sterile cotton balls, etc. (If you want to eat seafood, bring some norfloxacin and berberine or bezoar detoxification tablets).

8. Sunglasses and sun hats (there are many beautiful hats for sale in Sanya, you can buy them after going there). UV-resistant parasols (many hotels also have their own umbrellas).

9. Things girls should bring: high SPF sunscreen (recommended: SPF50 or above with high water resistance), after-sun calming repair lotion, moisturizing spray, whitening night cream, whitening mask, makeup remover Supplies, wet wipes, feminine products, shampoo.

10. Prepare a large travel bag as a backup (preferably a foldable fabric one). I believe you will be able to use it when you come back. Finally, don’t forget to prepare some snacks and foods you like.

Hainan, referred to as "Qiong", is a provincial-level administrative region of the People's Republic of China and the provincial capital Haikou. Hainan Province is located in the southernmost tip of China, bounded by the Qiongzhou Strait to the north and Guangdong Province, to the west by the Beibu Gulf and opposite the Guangxi Zhuang Autonomous Region and Vietnam, to the east by the South China Sea and facing Taiwan Province, and to the southeast and south by the Philippines, Brunei and the South China Sea. Malaysia is our neighbor. Sansha City in the province is the prefecture-level division with the southernmost geographical location, the largest total area (including sea area), the smallest land area and the smallest population in China.

Hainan is also known as Qiongya and Qiongzhou. In 110 BC, the central government established Zhuya County and Dan'er County on Hainan Island, which were under the jurisdiction of the Jiaozhou Prefect, marking the official inclusion of Hainan into the Chinese territory. On April 13, 1988, Hainan Administrative Region was separated from Guangdong Province and established as an independent province. Hainan Province and Hainan Special Economic Zone were officially established. Hainan Special Economic Zone is China's largest and only provincial-level special economic zone.
