Are there any ancient examples of loss of traditional culture due to foreign cultural invasion?

The Siku Quanshu has 3475 books, 79070 volumes;

Destroyed (books with only a title but destroyed): 6766 books, 93556 volumes;

There are countless books that have not been destroyed without being cataloged, and even if they have survived, most of the content of the books has been destroyed, deleted and altered, and the original appearance of the books and their true contents have been completely lost. The original appearance and true content of the book is already completely different. It can be seen that the books destroyed by the Qianlong revision of the Siku Quanshu were much more than those preserved. This is a great disaster in the history of Chinese culture!

On the "Siku Quanshu", Mr. Lu Xun said profoundly: "Now not to say anything else, but look at the Yongzheng, Qianlong two dynasties for the Chinese writings of the means, it is shocking enough. Destroyed, destroyed, deleted and so on and not to mention, the most insidious is to tamper with the content of the ancient books. The Qianlong dynasty's usurpation of the "Siku Quanshu" is many people praised as a generation of events, but they not only messed up the format of the ancient books, but also tampered with the ancient writings, not only hidden in the inner court, but also awarded to the literary style is quite strong, so that the world read the scholars, and will never feel that our Chinese authors, there have been a lot of Chinese authors, there are some of the backbone of the people.

It is true that Qianlong repair "Siku Quanshu", so that some of the orphaned books, good books are preserved, but more orphaned books, good books were destroyed, was destroyed, was tampered with. This is the unabashed promotion of small good and concealment of great evil! This is the Qing dynasty rulers of the sinister and vicious place, they did bad things, but also let those corrupt Confucian for them to sing praises, whitewash for "a generation of events", is now also some "experts and scholars" by the Qianlong led by the nose, pathetic!

Why did the Qing Dynasty rule, in fact, the reason is very simple: the Qing Dynasty rulers with unprecedented cruelty of the word prison of terror policy clampdown, suppression of intellectuals, by repairing the history of the book, the book of its counter, so that the world's intellectuals consumed the spirit of the search for the line of ink, drilling pile of old paper in the study of the evidence to achieve the confinement of thought, the control of people's hearts and minds of the sinister purpose.
