What does it mean that a tree has two vernal equinox colors?

Spring blossoms, grass grows and warblers fly, and the vernal equinox comes. The vernal equinox, in the three months of spring, divides spring equally and divides day and night equally.

The origin of solar terms was first seen in "Yao Dian, Shangshu": "It's time and destiny, respect for heaven, like the sun, moon and stars, and respect for people". But the vernal equinox, as the official name of solar terms, should be the first book written by,, Luo and others in the first year of Emperor Wu of Han Dynasty (BC 104). Looking at Yuefu poems in this period, there is a saying of "vernal equinox". For example, in Ge Yanxing, "Yan Ke came for a few days at the vernal equinox, and in February, the silkworm stayed awake for a long time." It is more common for later generations to enter poetry with vernal equinox. Let's enjoy the warm sunshine, bathe in the spring breeze, read poetry books and walk into the vernal equinox of ancient poetry.
