The unique good habit is that people in China like to take notes. Notes at the national level are history books, local chronicles at the local level and genealogy at the family level. These are thousands of years of Chinese civilization, the same strain, endless testimony. One of the typical manifestations is the meeting between the King of Qin and Mianchi in Wang Zhao during the Warring States Period in 279 BC. The king of Qin was drinking heavily and said, "I overheard the good voice of the king of Zhao." Please play the harp. " Zhao Wang played the piano, and the book before Qin Jian said, "One day, Qin Wang and Zhao Wang drank wine to make Zhao Wang play the piano." Lin Xiangru said: "Zhao Wang secretly heard that the king of Qin was the voice of the king of Qin. Please give him a bowl of entertainment." The king of Qin was furious and refused. So they went forward and knelt down to invite the king of Qin. The king of Qin refused to strike. Xiang Ru said, "Within five steps, Xiang Ru please spill blood on your neck." Think left and right like a blade, and think right like a slap. So the king of Qin is not worried at all, just preparing for a blow; For example, Gu's Proposal said: "One day, the king of Qin was beaten by the king of Zhao." Recently, Yanran Cliff Stone Carvings written by Xiongnu Ban Gu were found in Hangai Mountain, Mongolia, which once again confirmed the reliability of China's historical records.
