What do you mean, there is no way out when it rains in early winter?

It's sunny in winter, it doesn't rain in early winter, and it doesn't rain in early winter. Or "It rains all winter in early winter".

They are all related to solar terms, which means that if it doesn't rain on this day in early winter, it will be sunny all winter. If it rains in early winter, it will rain all winter, so there is no way out.

Because ancient times were dirt roads, it was muddy when it rained, which meant there was no way to go.

If you are satisfied, please accept it. Thank you.
