20 10 found an area of 24.79 square kilometers in Mudu Town and Xukou Town, Suzhou, where the Institute of Archaeology of China Academy of Sciences is located, while the site of Tongqi City (Wuxi is called Hehe Greentown) found in the border area between Wujin and Wuxi in Changzhou in 2008 was 2.95 square kilometers.
Compared with 24.79, the smaller one can never be the capital of Wu, one of the five tyrants. At the same time, Jinan, the capital of Chu State, covers an area of 16 square kilometers, and Linzi, the capital of Qi State, covers an area of 15 square kilometers. The kingdom of Wu and Lu wanted to compete for hegemony with the Central Plains, and the capital would not be shabby to only 2.95 square kilometers. Therefore, the largest city site of Suzhou Mudu in the late Spring and Autumn Period of 24.79 square kilometers should be the capital of the State of Wu.
As for the birthplace of Wu culture, it should be Changzhou and Suzhou. After all, from ancient times to 30 years ago, Wuxi is now a county under the jurisdiction of Changzhou and Suzhou respectively. Later, Yixing, Wuxi and Jiangyin counties under the jurisdiction of Changzhou and Suzhou were zoned out to form Wuxi. After all, it originated from the culture of Changzhou and Suzhou. Some people say that Wu culture originated in Wuxi, which is far-fetched.
One more thing, Taihu Lake was called Zhenze in ancient times, and it was very big in ancient times. Thousands of years ago, most of Wuxi's land was still on the surface of Taihu Lake. It is really far-fetched to say that something originated in Wuxi.
The above is just a brief introduction. For details, you can go to the library to consult ancient books and ancient geographical maps.
