There is no clear definition.
1. Ancient architecture refers to the historic civil and public buildings before the founding of People's Republic of China (PRC), including those in the Republic of China. In China, many ancient towns and most big cities still retain some ancient buildings. However, in today's great construction, we should treat and protect ancient buildings and their cultural characteristics with a development perspective; We should not only preserve the ancient architecture culture in the world, but also make the ancient cultural heritage have modern value.
Although some ancient buildings are far away from now, their cultures are still worth learning from. As descendants of the Chinese people, architectural culture is also a part of China traditional culture. We should not only develop modern architecture, but also absorb nutrition from ancient buildings, so as to walk out of the road of characteristic architecture in China and let the ancient architectural culture in China be inherited and continued.
