Why is the weather in Wuhan so changeable?

In fact, it is not the weather that is changing, but the personal mood. When a person is in a bad mood, he thinks it is bad weather. Only when we are happiest, no matter what the weather is, we will feel happy! People are fickle, so is the weather! So we should have a good mood every day, so no matter what kind of weather we will think it is good weather, won't we? Hehe, so have a good mood every day! So I won't complain about the bad weather.
