Evaluation of "Old Book of Tang":
Shi Chen said: Emperor Guanwen made many extraordinary fortunes and was clever and powerful. If you choose a good person, you will not be selfish to the party; if you lose your ambition, you will make the best use of your talents. Therefore, Qu Tu and Yu Chi were enemies and were willing to devote themselves to each other; Ma Zhou and Liu Jie were alienated from each other and died at Jun Heng. Finally, peace and stability, please forgive me. Try to discuss it: the foundation is moist and the clouds are booming, the insects are chirping and the katydids are jumping. Even though the sages of Yao and Shun could not bring peace to the people by means of 梼杌 and qiongqi, the wise people of Yi and Lu could not prosper for Xia Jie and Yin Xin. When the monarch and his ministers encounter such difficulties, they will make their eyes open and their hearts will be opened, and the insects will flow and the muscles will be promoted. The wisdom of Fang and Wei is not greater than that of Qiu and Ke, and those who can respect the Lord and protect the people will suffer in times of trouble. Kuang Zhou Fa and Zhou Cheng are hereditary, and I have a legacy. Compared with the magnificence of Han Wen and Han Wu, I am ashamed of how virtuous I am. His ability to listen without confusion and to follow good deeds can last for thousands of years, just one person!
