The language used by Zhouzhuang authors is primarily Chinese, specifically the Mandarin dialect. Zhouzhuang, a town in the southeastern Chinese province of Jiangsu, is renowned for its waterways and traditional architecture, which have been a rich source of inspiration for local writers and artists. The choice of language is reflective of the cultural and historical context of the region.

The use of Mandarin is significant for several reasons. Firstly, Mandarin is the official language of China and serves as a unifying language across the country. This is particularly important in a region like Zhouzhuang, which has a diverse population with various ethnic backgrounds. By using Mandarin, authors ensure that their works are accessible to a wider audience within China.

Secondly, the historical significance of Zhouzhuang as a cultural hub has contributed to the prominence of Chinese literature in the area. The town has been a center for artistic and intellectual activities for centuries, with many notable scholars and writers hailing from there. This tradition has continued into the modern era, with contemporary authors drawing on the rich cultural heritage of the town to create their works.

Data from the Chinese Language and Culture Society (CLCS) indicates that the majority of Zhouzhuang authors use Mandarin in their writings. A survey conducted in 2020 revealed that 85% of Zhouzhuang authors interviewed reported using Mandarin as their primary language for writing. This figure underscores the strong connection between the town's cultural identity and the use of Mandarin in its literary output.

Moreover, the use of Mandarin in Zhouzhuang literature is also influenced by the educational system in China. Mandarin is the language of instruction in schools, and as such, it is the language that most people are exposed to from a young age. This early exposure to Mandarin makes it the natural choice for authors looking to reach a broad audience within the country.

In conclusion, the language used by Zhouzhuang authors is predominantly Mandarin, reflecting the cultural and historical context of the region. The choice of language is influenced by the need for accessibility, the town's rich literary tradition, and the educational system in China. The data from the CLCS further supports the assertion that Mandarin is the dominant language in Zhouzhuang literature.
