Is the weather forecast really nonsense?

The current weather forecast is only to earn advertising fees, so we lied to everyone that our weather forecast is accurate to when it will rain. In fact, they are all released by the Central Meteorological Observatory. Is central weather bureau accurate for every region? Especially in the mountainous areas of Yunnan, Guizhou and Sichuan, that's impossible. So I'd better watch the satellite cloud picture by myself, and don't download any weather forecast APP. They just want to make money, even their father.
