Ming and Qing Dynasty is the peak of ancient craft technology, but also the era of ideological and cultural stagnation, I think a society if the thought is stagnant, there is no new theoretical breakthrough, will continue to increase its decorative and complicated under the old technology. Throughout the development of human science and technology, every time there is a technological breakthrough, its products are first pragmatism and then decorativeism, alternate development. I used to listen to people blowing, foreigners can repair churches for hundreds of years, Chinese do not have this patience. This has nothing to do with patience, foreigners repair the decoration to their gods, Chinese repair the decoration to their own home, if a family can continue, then his home can also be built for hundreds of years.
