Why is the weather forecast in Zhongshan not accurate at all?

The weather forecast abroad is relatively accurate. In the United States, each province has 4-5 measuring instruments. In China, there are only 1-2 instruments in each province, and because the coastal area of China will enter the "ocean peak period" in the next 20 years, typhoons will often interfere with the weather forecast. To be exact, the weather forecast is "sometimes" inaccurate; To be fair, weather forecasts are sometimes accurate.
