Will it get cold after the rain in early autumn?

Yes, every time it rains after "beginning of autumn", the temperature will drop to a certain extent, which is also the reason why the saying "an autumn rain and a cold" is here.

However, it doesn't rain after beginning of autumn. As a sign, "it rains in front of beginning of autumn and there is no drop of water behind beginning of autumn", the most direct consequence is obvious: "It doesn't rain in dry and hot autumn in beginning of autumn, and it rains in rainy autumn in beginning of autumn".

The experience summarized by farmers is that it rains in autumn, which means that it is mainly sunny for a period of time. If it rains in summer, the weather will be bad for a while.

If it rains in early autumn, it is suitable for harvesting crops next year. If it rains in summer, it rains a lot in autumn, which is not conducive to autumn harvest, and it can't get the sun after harvest.

Beginning of autumn has arrived, but not in autumn. The division of climatic seasons should be based on the "average climate temperature", that is, the local average temperature is below 22℃ for five consecutive days, which is the real autumn.
