Why can't the traditional architecture with China characteristics be well inherited?

The traditional architecture in China is developed from the ancient dry-column architecture, which is mainly manifested in the beam-column structure. The weight of the roof is supported by the pillars at the four corners, rather than the walls of western buildings. This ancient architectural art in China laid the foundation for the "frame-style" architectural structure that we commonly use today, which is actually a replica of the ancient architecture in China. Our ancient buildings are often described as "the wall falls down but the house doesn't fall down", because the ancient buildings in China are not load-bearing, so long as the pillars don't reach the house, they won't fall down. The main body of ancient architecture in China is wood structure, which has become the only architectural way in the world today and is an outstanding contribution of China people to world architecture.
