Today is 20 1, 2065438, and I am in Beijing. The weather is abnormal tonight. What happened?

Today is the summer solstice, and the weather on Boxing Day is usually different from usual. For example, the solar terms studied by the ancients are different in peacetime. Moreover, when it rains in Beijing, it's easy to squint at low pressure and high pressure, so hurry back to your room, because it's basically heavy rain, and there is indeed a lot of lightning, but it's all in the high clouds, so there is no danger of burning. This is easy to catch a cold, and it will catch a cold in a short time. Pay more attention to your health. I hope you have a good time in Beijing!
