Tang·Yuan Zhen

La wine is self nourishing in a bottle, with a golden furnace and animal charcoal warmth.

It is advisable to stay close to fire in the cold, and do not open the door when there is nothing to do.

Winter and spring alternate, but the moon around the stars does not exist?

In the Ming Dynasty, a new law was adopted, and plum blossoms and willows await the arrival of spring.

This is the final moment for all things to endure the harsh test, and also the key node for the hidden and silently sprouting of yang energy. Many agricultural activities have taken a break, and people are keeping warm and waiting for spring. There are folk customs that“eat glutinous rice”“Sweep dust”The custom of waiting is not only to keep warm, but also to bid farewell to the old and welcome the new. Although the Great Cold is extremely cold, it exudes the vitality of reincarnation——Under the ice, spring water has quietly begun to sprout.
