Why does it rain on July 7th every year?

On July 7, there may not be a smart cloud. On July 7th, it may not rain. Comparatively speaking, there are many days when there are clever clouds and rainy days, which is a high probability event. Especially when it rains. I've always thought, or my feeling is, it's best to have a little Mao Mao rain when it rains. It was the once-in-a-year Cowherd and Weaver Girl, who shed tears involuntarily when she poured out the suffering of lovesickness. Don't shed tears.

It rains on Tanabata, and Weaver Girl cries. I believe those are tears of regret. Year after year, sobs turned into wails, and it rained cats and dogs in Mao Mao. The rain that started on Tanabata this year lasted until the eighth night of July. At noon on the eighth day, the sun rain fell so rapidly that all the sadness was exposed to the sun without cover. At that time, the cowherd had returned to the world and began to look forward to the new year.
