Where are Chinese orchids suitable for growing?

Accordingto orchids'living habits of liking sun but fearing heat, liking wind but fearing cold, liking tree shade but fearing dust, and liking warmth but fearing smoke,when growing orchidsthe location of the site should, first, be as far as possible from pollution sources that discharge large amounts of industrial waste gases such as sulfur dioxide and hydrogen fluoride, as well as smoke and dust. Second, it should face southeast with its back directly to the northwest, so that it can avoid the strong evening sun and biting cold wind while fully enjoying the warm morning light and bathing in the mild southeast wind. Third, the terrain should not be low-lying, and there should be no high-rise buildings on the southeast side blocking wind and light. This is fromorchids'living habits' requirements. Of course, it is good to have such an ideal place, but it is not that without such a good site you cannotgrow orchids. For example, Chongqing, one of China's "three furnaces," often has temperatures as high as above 42°C, and the temperature difference between day and night is also very small, and as a heavy industrial area, its air pollution is severe, so it is called by well-known figures in the orchid world a "orchid-growingforbidden zone"; Shenyang's cold period lasts as long as half a year; Xi'an's climate is also relatively dry, and the external conditions are all unfavorable to the growth of orchid plants. But orchidgrowersin these places, adopting a scientific attitude and appropriately improving the harsh environment, have cultivated robust orchid seedlings that meet export standards. This shows that no matter which place or what natural environment, as long as it is appropriately improved to create environmental conditions that can meet the needs of orchid plant growth, orchids can be grown well.
