What does it mean that there is no rain in summer?

If it rains in summer, there will be more rain in the next period and the river will rise; On the other hand, if it doesn't rain in summer, there will be sunny days for some time, with little rain and dry soil. This kind of high temperature and little rain often ends after the "White Dew" solar term.

There is an old saying in the countryside that "a ditch falls in summer, and the drizzle drips into autumn", which means that if it rains in summer, and the rain is not small ("falling into a ditch" is a rainstorm), according to the experience of our ancestors, it indicates that there will be continuous rainy weather in the future.

There is also an old saying in the countryside that "the river is cut off when it doesn't rain in summer", which means that if it doesn't rain in summer, there will be little rain in the following period, and drought is likely to occur. Although the "cut-off" is a bit exaggerated, it indirectly shows that there has been continuous high temperature and hot weather.
