There is no Jia in the mountains, and I don't know the meaning of the year.

"There are no children in the mountains, and the cold doesn't know the year" means that because there is no calendar in the mountains, the slight cold and the great cold in the 24 solar terms have passed, and I don't know that the Spring Festival is coming.

It is said that the mountain is not a calendar, the stone monkey swims in the mountain, spring comes and winter comes, and the years pass unconsciously. Jiazi is a calendar of ancient years of cadres and branches, an ancient calendar of China, which is very scientific and a great embodiment of the profoundness of ancient civilization in China.

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.
