Why are there fewer mosquitoes in Sanya?

There are few mosquitoes in Sanya, because Sanya is close to the sea. Mosquitoes in Sanya generally live far from the coastline, and the wind at the seaside is relatively strong. The water by the sea is not conducive to their survival and reproduction, so there are few mosquitoes in Sanya. Sanya, a prefecture-level city under the jurisdiction of Hainan Province, was called Lucheng in ancient times, or Yazhou and Yaxian. It is located at the southernmost tip of Hainan Island, bordering Lingshui Li Autonomous County in the east, Ledong Li Autonomous County in the west, Baoting Li and Miao Autonomous County in the north and Nanhai in the south. Sanya is an international tourist city with tropical coastal scenery, also known as "Oriental Hawaii", and its unique coastal scenery is desirable.
