What's the difference between cloudy and cloudy days?

When listening to the weather forecast, we often hear meteorological terms such as "cloudy" or "sunny to cloudy" and "cloudy to cloudy". However, many people complain that the meaning of the word "cloudy" is unclear. Isn't it cloudy with no sun? Why is it different? In fact, "cloudy" weather is strictly defined and can be called "between sunny and cloudy" weather. Meteorologically, sunny days mean that the area covered by clouds accounts for110 ~ 4/10 of the sky area; Cloudy refers to the situation that there are 40-70% medium-low clouds or 60- 10% high clouds in the sky. "Yin" means that the amount of clouds in the sky accounts for more than 8/ 10 of the sky area. It's just that there are a little more clouds in the cloudy sky than in cloudy days. You can't see the sun on a cloudy day, sometimes you can see the sun on a cloudy day, and sometimes you can't see it.
