What does it mean that the peach blossoms in the Temple of the Mountain begin to bloom in April?

Peach blossom in Dalin Temple written by Bai Juyi, a poet in the Tang Dynasty: "Peach blossom in Mountain Temple begins to bloom in April. I hate that spring is nowhere to be found and I don't know where to go. "

In April of the lunar calendar, the flowers outside the mountain have withered, while the peach blossoms at Dalin Temple on the top of the mountain are in full bloom.

In April, the author accidentally swam to Dalin Temple on the incense burner peak of Lushan Mountain, only to find that the flowers at the foot of the mountain (so-called "human") had fallen and the peach blossoms on the mountain had just bloomed, but the poet wanted to explain not only natural phenomena, but his sigh should be some of his feelings about the world. Volume 43 of Collection of Bai Juyi has Preface to Dalin Temple: "Yu and Henan Yuanjixu, Middle School, Nanyang Zhi, Yu, An Dingliang, Zhang Te, Tuolin Temple Shaman, Zhi Man, Shi Jian, Li Bian, Dao Jian, Gao Yun, Xi Ci, Yan Hong, a total of 17 people. The forest is far away and inaccessible. Around the temple, there are many clear and pale bamboos, short and loose bamboos. There are only wooden houses in the temple, and all its monks are Haidong people. The mountains are high and deep, and the season is never late. So the month in Xia Meng is like a day in February, when pears and peaches begin to blossom and the grass is still short. The climate of the characters is different from that of the flat settlements. When you first arrive here, you suddenly realize that if you don't create a world. Because of the slogan quatrains. Then I looked around the wall and saw the names of Xiao Langzhong Village, Wei Langzhong Hongjian and Li Bububo. Because of the sigh with Ji Xu, he said: This is the first place in Kuanglu. From the post road to the mountain gate, there is no half schedule. Twenty years have passed since Xiao, Wei and Li You, and there is no successor. Well, so is the attraction of fame and fortune! Shi Yuanhe 12 April 9 Lotte Preface. " The contrast between the two poems can reveal Bai Juyi's mood.

The influence of temperature on biological physiological characteristics is explained from the biological point of view. Generally speaking, for every rise of 100 m, the temperature will drop by 0.6 degrees, so the solar term on the mountain will be late and the flowering will be late.
