On the problem of clearing and replenishing cool air.
I am in Hainan, and it is very common to enjoy the cool in Hainan. Basically, there are stalls on the roadside at night.
However, the coolness of Hainan generally does not use sugar water, but uses coconut milk or fresh coconut water to directly open the coconut and pour it out ~ and the material inside will also have coconut meat, which is delicious ~ ~ Hehe.
