What practical problems did the experience of heavenly creations explain?

To control a country, a nation and enslave a nation, we must first fool their thoughts. The best way to fool their thoughts is to combine rigidity with softness. Just for a war, all opposition voices were stifled and words were destroyed. In the name of compiling Sikuquanshu, countless books were destroyed, and China's books of past dynasties were edited and destroyed. Then the tampered junk works are distributed to all parts of the country in the official form for a new generation to learn. Wu Kai in Tiangong is just one of them. It is also one of them, and there are many books and masterpieces, but unfortunately they have not escaped this robbery!
