A poem describing old age

This poem describing old age is as follows:

The first song: "Jia Xu" Tang Du Fu is not self-controlled, and the autumn wind blows. Spend Albert Venn Dicey for a while, but a few leaves sink. The weak spring breeze came early, and the long night was full of dew. Shake it down after the rivers and lakes, and you are afraid to waste your time.

What should I do if I can't save myself in the face of destruction and am blown away by the autumn wind? It only blooms in a very short time, and soon the leaves will sink into the water. When the body is weak, the spring breeze blows too early, and when it grows into a dense cluster, there will be more cold dew at night. Even if flowers and leaves rot and shake off, I still worry about wasting time.

The second song: "Baifafu" Zuo Si in Wei and Jin Dynasties? White-haired stars are born in temples. Although it is not a green fly, it is a dirty instrument. Look at the name of the country in order to find fault. I pulled out the pliers, and the good title was Yan.

Interpretation: white hair, starting from the sideburns. Although not blackfly, but also detrimental to the appearance. Being an official is laughed at. I will pull it out with tweezers, just for wealth and salary.

The third song: "Appreciating the Happy Days and Seeing the Old" People in Yuxi, Liu Tang, who don't care about being old, will have pity on those who are old. The body is thin and the frequency is reduced, and the hair is thin and the crown is self-biased. Waste books cherish eyes, and moxibustion is mostly for years.

Interpretation: Who doesn't worry about being old, and who will show love to him when he is old? As the figure becomes thinner, the belt will become tighter and tighter, and the hat with sparse hair will lean to one side. The reason why the book is put aside is to care for the eyes, because moxibustion is often used in the elderly and infirm.
