What happened to willow leaves around the winter solstice?

In early winter, the willow branches are still green and soft, and the willow leaves are still green. Some veins are slightly yellow, so they can't be pulled off with a light pull. White buds the size of needle cones grow on the roots of willow leaves.

During the period from winter to the future, willow leaves changed from turquoise to light yellow, and then all turned golden yellow after being hit by cold, frost and rain. Then all the leaves of the willow tree fell, and the willow tree with all the leaves fell, bent down and danced in the cold wind, which made it more vibrant.
