Ok, I'll tell you about our high school Chinese teacher's analysis of why some talented people in history were not included in the textbook. I hope it helps you.
First of all, the most fundamental factor is that textbooks are designed to standardize people's thoughts, cultivate people's sentiments and carry forward and inherit the culture of the Chinese nation. The choice of textbooks from primary school to high school is very important.
Anyone who can participate in editing the textbooks of Chinese studies can be regarded as a master of Chinese studies with profound attainments. It is absolutely impossible to say that a talented person has been forgotten by them.
The only reason is that the poems or life stories of those gifted scholars are contrary to the cultivation of positive national cultural spirit. China's culture is vast, and there are too many complex and inclusive standards, which leads to their being banned, and other ancient people have entered modern culture textbooks.
Tang Yin's poems are quite bold and somewhat self-concealed. "I don't see the tomb of Hao Jie in Wuling, no flowers, no wine and no hoe." His seclusion is different from Tao Yuanming's enjoyment of nature, and he never forgets to feel the philosophy of life. Between the lines of the Tang Dynasty, he is more hedonistic and negative.
In addition, the film "Tong Pak Hu Dian Qiu Xiang" completely subverts the original attitude of a scholar.
What we can do is to put aside glitz and explore the soul of literati.
