The ancients called spring buds "youth", which means that spring is full of vegetation.

The poem says, "But an inch of grass is worth three springs", in which "three springs" refers to spring. There are three months in each quarter. In ancient times, people called the first month of the lunar calendar Meng Chun, February Midspring and March Ji Chun, which were collectively called "Three Springs".

Some people mistakenly understand "three spring" as the third month of spring, but it is not. Zhong Nanshan Fu by Ban Gu in Han Dynasty wrote: "The season of three spring, the beginning of summer dream, the sky is clear and clear, all around." In the Tang Dynasty, Li Bai had a poem "Don't Feel the Account": "Leave hate in March, and the ceremony is in October." There are two sentences in Song Fanghu's "Fighting Quails and Going Green" in the Yuan Dynasty: "The beautiful scenery in March is magnificent." Liu Dabai said in the poem "Spring has passed": "Three spring has passed, how many spring marks should be left." The "three springs" here all refer to spring, not March or March.

"Yangchun" is another name for spring in ancient times. "Spring calls me to smoke, and I write long articles." In Li Bai's poems, "spring" still refers to spring. "Drunk Song", a piece of cloth on the Tang restaurant says, "What's the weather like in spring? Everything is thriving. " Not only the "Yangchun" in these poems is spring, but even Yang Chun, a county-level city under the jurisdiction of Yangjiang City, Guangdong Province, is named after the meaning of "the desert is hot and the seasons are like spring".

Spring is beautiful, and "Qingyang" has become the nickname of spring. This is also the meaning of "green sun" in Chen Ziang's poem "Experience", "If the day does not return, the green sun will wither". Qingyang County, Chizhou City, Anhui Province, Qingyang Town, Jiangyin City, Jiangsu Province, Qingyang Town, Sihong County, Suqian City, Qingyang Town, zouping county, Binzhou City, Shandong Province, and Qingyang Street, Jinjiang City, Fujian Province also have the meaning of spring.

"Sing my songs loudly and drink deeply, and start my home on a green spring day." The "youth" here does not refer to the age of teenagers and young people, but refers to the lush vegetation in spring, which is also synonymous with spring. There is a saying in "Songs of the South": "Youth fades, but the sun shines only." Wang Yi commented: "Green, the position of Dongquan, its color is also green." In the Ming Dynasty, Liu Ji's "The Wind Into the Pine" chanted: "Only if you don't know how deep the fragrance is, you will thank your youth." There is also the "youth" in Mr. Li Dazhao's poem "Time", which means "it is best to be a teenager in a lifetime and a youth in a year".

In the folk, people call the first month Meng Chun, early spring, first spring, early spring, last spring, Shouyang, Yuanyang, Wangchun and Zhengyang respectively according to the solar terms and farming, call February Midspring, Han Chun, Dazhuang, Zhonghe, Zhongyang and Yangzhong, and call March Ji Chun, Late Spring, Sanchun, Bianchun and Chunqi.
