There are no children in the mountains, and the cold does not know the year.

"There is no armor in the mountains, and the cold doesn't know the year", a proverb, which means that without an almanac in the mountains, the cold won't know that it has reached the first day of the New Year, which means that people living in the hinterland are isolated from the world and don't know festivals and things.

From The Journey to the West, I answered a man, a hermit in the Tang Dynasty: I occasionally came to sleep under a pine tree, and the pillow was a stone high. There is no calendar in the mountains, and I don't know what month the cold used to be.
