Zhang Yong's Sentence written by Song Dynasty is a volume (general edition). The Analects of Confucius has been a doctor since Emperor Wen of Han Dynasty. Mencius According to Zhao Qi's inscription, Wendi also tried to establish a doctor. As it rotates, history is not included. For two articles about the Doctrine of the Mean, see the Literary Annals. Dai Qing's The Doctrine of the Mean (Volume II) and Liang Wudi's The Doctrine of the Mean (Volume I) can be found in Sui Shu Jing Ji Zhu. But "University" has no other origin since the Tang Dynasty. Sima Guang's Historical Records contains an Introduction to Universities and an Introduction to the Doctrine of the Mean, both of which were written before Cheng Cheng, and neither of them started from Confucianism in Luo Min. Particularly detailed, starting from the second trip; In the name of "Four Books", it began in Zhu. Originally, The University, The Analects of Confucius, Mencius and The Doctrine of the Mean were the first. The four books, namely, The University and The Doctrine of the Mean, have few pages and are one volume, so The Doctrine of the Mean was moved before The Analects. The proposition of imperial examination in Ming Dynasty moved the golden mean before Mencius. However, it has nothing to do with the grand purpose and is not necessarily the same. The ancient edition of "University" is an article. Zhu Zefen divided the Classic and Biography, reversing its old times and filling its missing items. The Doctrine of the Mean is not a chapter divided by Zheng Zhu. So they are all called "chapters". The Analects of Confucius and Mencius combined various theories, so they were called "concentrated notes". Commenting on the Analects of Confucius, the eight theories are called "the set of solutions". But Yan's note has his surname, while Zhu's note has or does not have it, which is slightly different. There are many similarities and differences between Confucian thoughts in the chapters and sentences of Daxue. But the so-called "honest man" is used in the following old articles, and the creator only makes up one chapter of biography unless it is added to eight items. Harmless to reason, not beneficial to scholars. Why compete in different fields? Although the Doctrine of the Mean does not follow Zheng's annotation, it is more accurate than Zheng's annotation. In textual research, Song Confucianism is not as good as Han Confucianism; The study of righteousness and reason is not as good as that of Song Confucianism. When you say what you say, you must do it in your own way. For example, the words "don't be cautious about what you don't see" in Zheng's notes are not without its meaning. The section "Although it has its place" has not completely attacked its text. It's instructive to watch it go and get it, especially if you don't have to compete with the ancient meaning. There are also many annotations in The Analects of Confucius and Mencius. For example, the article "Hu Lian" in The Analects of Confucius is inconsistent with "Tang Ming Wei", and the annotation of Mencius' "Cao Jiao" is inconsistent with "Chunqiu Zhuan", which may be doubted by critics. I didn't know that "Hu Lian" used "Bao Xian as a note" and "Cao Jiao" used "Yes", which was not invented by Zhu. Another example is "The Wall of Counting Owners", which is marked with "mowing seven feet", "digging nine wells to mow grass" and "mowing eight feet", which is particularly contradictory. I didn't know that Seven Feet also included salty notes, and Eight Feet was also Zhao Qi's note. This is a matter of understanding and casting opinions, not out of personal opinions. If you don't know what the exam is, you can't learn from the teacher's heart. Generally speaking, Zhu devoted all his energy to the four books. His analysis of doubt and discrimination is far less than Yi's Biography of Ibn and Poetry. When reading his books, we should take righteousness as the foundation and seek its essence. Since the Ming Dynasty, those who attacked Zhu ignored his fame and wealth, while those who admired Zhu took care of it. Is Zhu Zhushu a universal view?
