Can Grain Rain sweep the grave?

Grain Rain can sweep graves. It's just that different places have different customs and there are some differences.

There is a saying that Grain Rain does not sweep graves:

1, Grain Rain, is the season of crop growth. We need to take good care of these lifeblood and work hard, so we should pay homage to our ancestors in front of Tomb-Sweeping Day, Grain Rain.

2. Grain Rain's tomb door has been closed, and the ancestors such as paper money can't get it, so they rushed to Tomb-Sweeping Day before Grain Rain to worship their ancestors.
