"Everyone sweeps the snow in front of the door, and never mind the frost on other people's tiles" comes from Zhang Fengyi's Notes on Irrigation and Enlightenment in the Ming Dynasty. The whole sentence is:

"Let's go in. Let's clean up the snow in front of the door, no matter whether he is frosted. "

Interpretation: Just clean up the snow in front of your own house, regardless of whether the snow on the tiles of other people's houses is cleaned up, especially don't mind your own business.

Extended data:

This sentence has different meanings in ancient and modern times:

Ancient meaning:

In the Song Dynasty, there was a similar saying in Chen's "Guang Shi Xun": sweep the snow in front of your own house and ignore the frost in others' homes. In ancient times, this sentence meant doing your own thing. Whether others sweep the snow or not, you should do what you have to do. This is a warning motto with positive significance.

The significance of modernity:

In modern times, this sentence has another explanation, referring to people who are insensitive to bad phenomena and turn a blind eye. Many people are indifferent to other people's homes with the attitude of not helping others, and only care about whether there is snow in front of their own homes.
