No matter what ancient town, there are people selling silk, key chains, and handmade jewelry. Even "special snacks" have become stereotyped. Stinky tofu, sausage, steamer cake... Since then, the ancient town has gradually become more and more similar, and the shops and special snacks in the ancient town have become more and more similar. Similarity has gradually replaced the uniqueness of each ancient town. According to reports, the "duplication checking rate" of ancient towns across the country is even as high as 99%, and related topics have also made the hot search list. The so-called "ancient town" generally refers to a commercial market town with a history of over a hundred years and still well preserved large-scale ancient residential buildings. Due to China's long history and a considerable number of existing ancient towns, through protection and development, ancient towns have become well-known tourist attractions around the country, bringing tourism revenue to the local area and meeting the needs of tourists for "poetry and distance". However, when tourists visit multiple ancient towns, they will find that there are few ancient towns with unique personalities, and most ancient towns are almost "carved from one mold.". Lin Peng, President of the Chinese Academy of Ancient Cities and Culture, once pointed out, "There are more than 2800 ancient towns in China that have been developed or are under development, and the number rate is probably the first in the world. However, how many can be truly remembered by people?" The implication is that most ancient towns are too similar. A university professor also pointed out that tourism in ancient towns has often become a unified mode of shopping, drinking tea and eating, and visiting performances. So are most ancient towns already "similar" or "similar" after development? It is not excluded that some ancient towns in the south or some ancient towns in the north are similar in some aspects due to their geographical and cultural proximity. For example, some ancient towns in the south have similar ancient buildings, similar slate roads, and similar small bridges and flowing water. However, there is a high degree of similarity among ancient towns in various regions, mainly after commercial development. Most ancient towns have become less and less distinctive in terms of retail goods, "specialty snacks", and other aspects, as homogenization has become increasingly serious. From a positive perspective, businesses in multiple ancient towns are good at "learning", and they should follow the trend in a timely manner as to which products are easy to sell in other ancient towns. However, from another perspective, this will do harm to the ancient town: first, the unique historical culture of the ancient town will be diluted by homogeneous goods and services; Secondly, excessive commercialization gives tourists the impression that the ancient town has become a "grocery store"; Third, the attraction to tourists will decrease. For tourists, visiting an ancient town is the same as visiting ten, and there is no need to pursue "poetry and distance.". The pursuit of commercial interests in the development of ancient towns is understandable. After all, investors need commercial returns, surrounding residents need income, and the local economy also needs the contribution of the tourism industry. However, in pursuit of commercial interests, it is not necessary to take the road of homogenization, because only by maintaining its own characteristics can ancient towns remain invincible in the competition and attract tourists for consumption. Taking the road of homogenization seems to have a relatively fast return on investment, but in reality, it is short-sighted and easy to make tourists "tired of reviewing the past". Therefore, it is not easy to make lasting profits. Some people believe that the homogenization of ancient towns is actually "hollowing out", which has some truth. Due to homogenization, the ancient town has weakened or lost its due charm and value. Therefore, the developers of ancient towns who have lost their way urgently need to return to "solidity" and truly create their own unique literature
