1, from a geological point of view. The geology on the east and west sides of Erhai Lake is completely different. Cangshan Erhai Lake was formed by the collision between the Indian Ocean plate and the ancient Yangtze plate. During the collision, the ancient Yangtze plate was cut under the Indian Ocean plate, forming Erhai Lake. When the Indian Ocean Plate was jacked up, Cangshan Mountain was formed. Therefore, the east bank of Erhai Lake is limestone karst landform, which can not store water. You will understand when you go to the local area. There are barren hills and sparse vegetation here, and the location of Dali Airport is called "Huangcaoba", which makes sense. On the west side of Erhai Lake are sedimentary rocks, which can store water. Cangshan has dense vegetation and gurgling streams. The only thing better than the west coast is that the scenery is better than the west coast. Seen from the east coast, Cangshan Erhai Lake is far more spectacular and beautiful than the west coast. But if you think about it, it goes without saying that if you are a fairy, you'd better live in Penglai Island or see Penglai Island from a distance.
3. From the meteorological point of view. Dali is located in the southwest monsoon belt, and most of the wind blows from the west coast to the east coast every year. Just look up the wind map of Dali on the Internet, so the polluted air on the east coast is definitely heavier than that on the west coast. Therefore, Dali's residential buildings are characterized by sitting west facing east, which is different from the traditional pattern of sitting north facing south in China, so that the wind blowing from west to east is not easy to blow into the house. Therefore, one of the three treasures in Dali is "the wind blows the courtyard to sweep the floor", and the houses in Haidong, especially those near Erhai Lake, can only sit east and face west, so the wind can easily blow into the house. In addition, when the sun rises very high in the morning, the east coast can only see the sun, while the west coast is beautiful to watch the sunrise. In the afternoon, the sun shines brightly on Erhai Lake, and the water surface directly reflects to the east coast, while the west coast does not have this problem.
3. Analyze from a historical perspective. Historically, Nanzhao State and Dali State were both established on the west bank of Erhai Lake, among which Dali State was the longest-lived dynasty in China feudal society, but its national heritage has been on the west bank of Erhai Lake, with little development on the east bank. At present, most historical sites in Dali are located on the west bank of Erhai Lake. On the east coast, there are only Shuanglang (fishing village), Nanzhao Fengqing Island (artificial scenic spot), Jinsuo Island (fishing village) and Tianjingge (newly built scenic spot). The only historical reason is Xiao Putuo. The ancients paid much more attention to the place of residence than modern people, that is, they paid more attention to Feng Shui. It is not without reason that they chose the west bank of Erhai Lake.
4. Analyze from the real environment. The west bank of Erhai Lake has long been the main residence of Dali, so all kinds of conditions are complete, such as transportation, shopping malls, markets, schools, hospitals, entertainment and so on. And the east bank of Erhai Lake is much worse. You can go to the local area, such as Dali House, and you must drive to buy a dish. When these facilities are almost built, maybe n years have passed. Although the government now strongly supports the development of Haidong and recommends Haidong Real Estate, it also proves from another aspect that Haidong was worse than Haixi. Whoever doesn't keep good things for himself, I recommend it to you and learn from Lei Feng.
