I am a tramp, because I don't have my own property, so there is nothing left around me except some books. But I didn't have my own bookshelf in the early days because I had no fixed place to live. I just built a temporary bookshelf with wooden boxes for packaging, so there are not many books, but they cover a wide range and are very useful, which solves many problems in my work. But in the end, because individuals wandered around, they lost one place after another, and lost hundreds of books for decades! In about 2005, I bought an old bookshelf. The quality is good, but it is a little small and the books are limited. I have several boxes of books under the bed. In July 2007, I bought a used computers, learned how to type, entered some important documents into the computer years ago, and needed to publish articles online. My wife and I had an argument about surfing the internet, which turned out to be the fuse of family breakdown. I have to leave my home where I have worked hard for 14 years. Naturally, I left my cherished home with my used computers, books and bookshelves without asking for anything in return. In order to facilitate transportation, I sawed the bookshelf in half and went back to my hometown in Shandong. I don't actually have a house. What do I have in my hometown? At this difficult time, I moved into Jihu Town Sanatorium, my new home. In this way, all my belongings moved to this new home, including my bookshelf. Later, a stack was added between the bookshelves of these two parts, which can store twenty or thirty more books, but this floor is not filled with books, but with some daily necessities. Although the growth rate of paper books has slowed down in recent years, there are still dozens of books, with books on the shelves and under the beds. The computer is convenient and the network is convenient, so many of my documents are stored in the U disk in different folders in my computer. Some documents have also been published on the Internet, including: Goldbach's conjecture proof, the road to a strong country in mathematics, the mathematical program-micro mathematics and macro mathematics, the solution of Euclid's geometric parallel problem, on the reduction to absurdity-a living universal axiom, the basic theory of light and other papers, and the novels "The Circle" and "The Rubik's Cube is not magic" In addition, my library Baidu Library has 350 books.

I live in Jihu Town Sanatorium. One of my nephews came to see me and brought a pack of nutrition. The outer packaging is gorgeous, but there are two ordinary flours in the inner packaging. Although the inferior coarse porcelain cup is not good, I didn't throw it away, but made a pen container. I don't write in brush very often. There are several brushes in the bookshelf. In the pen container, there are ballpoint pens, fountain pens and thermometers. I was healthy and less ill decades ago, but now I am eighty years old and my health is not as good as before. I have caught a cold almost every year in recent years, so I brought my own thermometer for self-examination and bought some medicine for treating colds nearby. It will be fine in three to five days. Although I paid for it myself, it was only about twenty or thirty dollars, which was nothing. On this issue, I didn't go to the hospital for treatment according to the dean's "instructions". Although I can be reimbursed in full, I have my own principles and am unmoved, saving 200 medical resources to 300 yuan for the society.

Cactus is drought-tolerant, absorbs less water and nutrients, and can grow. I had a hard time, but my life came back, just like a cactus.
