I will travel to Hainan soon. What good things can I buy?

Look at the weather forecast before you come. If it is cloudy and windy, the temperature is still low. It's best to prepare some warm clothes (my parents didn't bring clothes after coming to Haikou, so I bought them some warm clothes). However, if the sun shines, the temperature will rise immediately (the temperature has dropped recently, about 24 degrees at night). I am in Haikou, and I hope the following information will help you. Hainan tourism notice 1. If it is sunny, it will be very poisonous. It is necessary to wear sports shoes instead of leather shoes to prevent sun exposure. You need to bring sunscreen products, including sunglasses, umbrellas and sunscreen. 2, eat seafood by the sea, seafood is of course the first choice, but you must not eat too much. In order to prevent accidents, you need to bring digestive AIDS and anti-inflammatory drugs. If you don't have local friends to lead you, you'd better not eat the food on the stall. There are many kinds of fruits in Hainan, such as coconut, mango, betel nut, pineapple and jackfruit. They are sold in street stalls, but you should not eat too much, but you can take some home and check them on the plane. 4. Hainan specialty coconut carving, shell carving, coral bonsai, pearls and crystals must be carefully identified when buying, and the price should be clear. Don't buy anything above 100 yuan or high-end things, otherwise it will be Zhou Yu's yellow cover. Coral is strictly prohibited from boarding. 5, free activities try to avoid acting alone. Colleagues' cell phones and room numbers must be remembered. Remember the name and location of the hotel. Six cameras. The camera battery, film, adhesive tape and charger should be well prepared. Don't be stingy with your movie, or you will regret it when you get home. When playing on the beach, be careful not to let spun yarn or seawater enter the camera equipment. 7. With regard to consumption, the consumption level in Haikou is relatively lower than that in Sanya.
