At the end of Ming Dynasty, Fang Yizhi's Little Knowledge of Physics quoted an earlier exposition of Wu Kai in Tiangong. At the end of the Ming dynasty, someone carved the second edition and prepared to publish it. Due to the demise of the Ming Dynasty, Tiangong Kaiwu was not published in the Qing Dynasty, but disappeared in China for political reasons. It was not until the early years of the Republic of China, more than 300 years later, that a man went to Tongzhi, Yunnan, and found a book named Tiangong Wu Kai quoted in the place where copper was being smelted. So he wanted to see the whole picture of the book, so he went to major libraries in Beijing to search for the book. As a result, he found nothing and asked all kinds of book collectors, and no one knew about the book. That is to say, after nearly 300 years of Qing dynasty rule, this man happened to find the Japanese version of this book at a Japanese friend's house, so he went to the Japanese library to check it out. This inspection has nothing to do with it. He found that the book has been translated in Britain, Russia, Germany, Japan and France.
Because there is a strong sense of "distinguishing between China and foreign countries" in a large number of ancient books in China, in order to consolidate the rule as an alien and eliminate the subjective consciousness of the Han nationality, the ancient books in China were centralized, inspected, revised and destroyed, which is also commonly known as the "Sikuquanshu". Among them, those that were considered unfavorable to the Qing Dynasty were modified or destroyed. Tiangong Kaiwu was destroyed by the thought of "anti-Manchu". Later, Heavenly Creations was reprinted by Japanese edition in China. -"Heavenly Creations" was slightly extracted from "Integration of Ancient and Modern Books", but it was lost in China because of the suppression of anti-Qing thoughts in the revision of Sikuquanshu. At Tianyi Pavilion in Ningbo, Zhejiang Province, its first engraving has been preserved so far. However, it was not publicly issued in the Qing Dynasty.
