Geographical location is not dominant. He Hong is very cheap. As long as Sanya has a little sea view, or a little 2-3 kilometers near the sea, the unit price is generally not less than 20,000 yuan/flat, but He Hong is not near the sea, but on the mountain, so the price is cheap. Sanya, called Lucheng or Yazhou in ancient times, is a prefecture-level city under the jurisdiction of Hainan Province, People's Republic of China (PRC). Sanya is located at the southernmost tip of Hainan Province, with a total land area of 192 1 km2 and a sea area of 3,226 km2.
