Can Wuhan lawyers fight Hanchuan's lawsuit?

Of course.

In the Law of People's Republic of China (PRC) on Lawyers, there is no provision that lawyers cannot engage in litigation activities in different places. Lawyers can not only participate in litigation activities, but also accept others' entrustment as legal advisers and provide some other non-litigation legal services.

Hanchuan is located in the middle of Hubei Province, the hinterland of Jianghan Plain, the lower reaches of Hanjiang River, and close to Wuhan, the central city of Central China. It is an important part of Wuhan city circle. The transportation in the territory is convenient, and Wuhan City Circle passes through the expressway around the city (Wuhan Sixth Ring Road, Hubei Expressway S43), Shanghai-Chengdu Expressway (G42), Shanghai-Chongqing Expressway (G50), G348 National Road, Hanji Railway and Hanyi Expressway.
