1. As we all know, ancient Chinese has four tones: Ping, Shang, Qu and Ru. But do you know who summarized and discovered this rule in history? He is Shen Yue of the Southern Dynasties. He first discovered the four tones in Chinese, and wrote a monograph "Four Tones Spectrum". However, Liang Wudi is very disdainful of his academic performance and always thinks he is talking nonsense. So once, Liang Wudi asked another phonologist, Zhou She, "What are the four tones?" Zhou She replied: "The sage of the son of heaven is also." According to the word "Tian Zi sage", the sky is flat, the son is rising tone, the sage is falling tone, and philosophy is entering tone. 2. During the Northern and Southern Dynasties, Xiao Daocheng, the Emperor of Qi, liked calligraphy. At that time, there was a great calligrapher named Wang Sengqian. Once, Xiao Daocheng and Wang Sengqian competed in calligraphy to see who wrote well. Write separately and then judge each other. Xiao Daocheng asked Wang Sengqian, "Who do you think is the first?" Wang Sengqian glanced at their words and thought that even if he was the emperor, he could not speak with his conscience. So Wang Sengqian replied: "I am the first in the book, and your majesty is the first in the book." 3. On one occasion, Master Sima had dinner with Yu Zhong (son of Zhong You, brother of Zhong Hui), Chen Tai (son of Chen Qun) and Wu Chang (son of Wu Zhou). Sima Shi and other people mocked Yu Zhong and deliberately asked him, "Who is Gao Yao?" -What's the problem? In ancient times, it was impolite to mention the names of elders in person. Yu Zhong's father's name is Zhong You, so Sima Shi and several others deliberately asked "Gao Gao". What did Yu Zhong say? He replied, "Ancient wisdom." In ancient times, a noble man quietly brought it in in the name of Sima Shi's father. That's not all. Later, he said to Chen Tai and Tachileik, "A gentleman is not a party." A gentleman should be honest and honest, and not form a party for personal gain. It's simply low-level for you to bully others in partnership. At the same time bring in the names of Chen Qun and Wu Zhou. During the Three Kingdoms period, Liu Bei once sent Yi Ji to Wu Dong. After Yi Ji arrived in Wudong, he visited Sun Quan. Slag spring glanced at Yi Ji and thought, I have to give him the arrogance to kill Liu Bei. So he began to comfort Iggy: "It's really hard for you. It must be hard to serve a ruthless king, right? " What about the king who can't work? After listening to this, Yiji replied sincerely: "Where, where, as long as you stand together, it is not difficult at all." It is not enough to worship together. Shi Zhongli, the foreign minister of Song Dynasty, was the son of the famous Shi Xizai. At that time, the royal family kept many animals in Yujin Garden. Shi Zhongli went to the zoo to see lions with his colleagues when he was free. The breeder told them that lions eat ten pounds of meat every day. Hearing this, my colleagues expressed their feelings and said, "The treatment of our officials is not as good as that of a lion." Shi Zhongli said seriously: "Our officials are all foreign ministers. Dare you look at the lions in the garden? " We are all foreign ministers, how can we compare with the lions in the garden?
