Why does it rain after some people die, especially when they come out of the mountain?

There is no scientific basis for this. Rain and sunny days are natural phenomena and have nothing to do with the death of the elderly. However, some old people said that if a loved one dies, or it rains on the day of the mountain, they will be sad and "shed tears" tomorrow, indicating that the old man who died has worked hard all his life, and even the old man feels sad.
