It will be rainy and rainy every year on Valentine's Day. Why?

On Tanabata every year, countless magpies fly into the sky and build a magpie bridge to let the cowherd and weaver girl cross the river to meet each other. It is said that there will be fewer magpies in the world on Tanabata every year, because they all fly to the sky to build bridges. And after Tanabata, the hair on the magpie's head will fall off, because Tanabata went to bridge the bridge. Some people say it will rain on Tanabata night, which is the tears of joy after the reunion of Cowherd and Weaver Girl.

The phenomenon that it often rains on Tanabata should be a climate law. In July, it was rainy in most places, and with the ancient legend, people felt that it would really rain on Tanabata.

In addition, many legends are based on some realistic laws, which is why these legends can be circulated for thousands of years. Our ancestors were really great, and the solar terms in our lunar calendar were so in line with the laws of nature. Therefore, the legend about the rain on Qixi Festival is also a summary of the laws of nature by our ancestors.
