Mo Daosangyu night, the sky is full of clouds. The whole poem:
Whoever does not care about old age will have pity on him.
The body weight loss is frequent and the hair is thin and the crown is deviated.
Discarding books means cherishing the eyes, and using more moxibustion means passing the years.
Those who have experienced things are still familiar with things, and those who read people are like reading the river.
If you think about it carefully, you are all lucky, but this will make you sad.
Mo Dao Sangyu is late, and the sky is still filled with clouds.
"Don't let the mulberry trees bloom at night, the sky will still be full of clouds" was originally a poem by Liu Yuxi of the Tang Dynasty, and later evolved into a Chinese idiom, which means that you will get stronger when you are old, you will be able to do something, and you will be proactive.
Creative background
In 836 AD (the first year of Emperor Wenzong's founding), the sixty-four-year-old Liu Yuxi branched off to Luoyang, the eastern capital, as a guest of the prince; at this time, his Bai Juyi, his contemporary, has been living in Luoyang for three years with the same identity.
Finally we got together, and we were both very happy. However, Bai Juyi expressed a negative and pessimistic mood about aging in his poem "Ode to the Elderly and Gifts of Dreams" written to Liu Yuxi, and Liu Yuxi wrote this poem in response.
