? The vast China has thousands of years of civilization, numerous historical records, and numerous characters. The great sages used words to rule the world, or taught by example to shape the country. Their words of self-cultivation and destiny, strategies for governing the country and the peace of the people, their beautiful words and sentences, and their candles reflecting the blue sky. Emperor Taizong of the Tang Dynasty said to his courtiers: "I use copper as a mirror to straighten my clothes; I use ancient times as a mirror to know the ups and downs; I use people as a mirror to know gains and losses. I always keep these three mirrors to prevent my own mistakes. Now that Wei Zheng is dead, one mirror is dead!" He cried for a long time. People are not sages, how can they have no faults? There is no greater good than changing it! Emperors still have human mirrors, how much more so than ordinary people!
