After reading The Great Adventure of Qin Shihuang's Mausoleum, I feel that my knowledge is still not enough, and my understanding of history is still too little. The Great Adventure of Qin Shihuang's Mausoleum is mainly about Qin Shihuang's underground palace. I admire the author's imagination, and Qin Shihuang's underground palace is also vividly written. It seems that the author really has a wild imagination. In the article "The Great Adventure of the Mausoleum of the First Qin Emperor", I learned that martyrdom is a funeral custom in which people or objects are buried with the deceased. I also know that earthquake refers to the violent movement of some rocks that make up the earth's crust, which produces seismic waves, thus causing the earth's surface to vibrate. Usually, earthquakes are caused by the dislocation and fracture of rock strata in the deep underground. After reading it, I admire the author very much, and his unrestrained imagination deeply touched me. I want to improve my imagination. I also learned from books that Qin Shihuang built so many buildings. Being reviled by millions of contemporary people, because Qin Shihuang made great efforts to build a building, Qin Ershi Zhao Gao finally sealed 100,000 craftsmen in the underground palace. But it has brought such huge economic benefits to future generations. This is the irony of history. After reading this book, I also have great respect for Qin Shihuang, because I found in the book that Qin Shihuang Ying Zheng has been leading the government since he was 13 years old. Moreover, the bronze swords found in the terracotta warriors and horses have been very sharp for more than 2,000 years. Some researchers folded it with a stack of paper, and the sword easily pierced the stack of paper. There are as many as 19 sheets of paper. The reason why the sword has not rusted for more than two thousand years is that the surface of the sword is covered with a layer of chromium oxide. Chromium treatment technology was patented by USA 1937 and Germany 1954. China had this technology 2,200 years ago. It's incredible.
