You need to see the context. Wuxi is between Shuzhou (10m) and Nanjing (8.8m), next to Shanghai (26m) and Hangzhou (21m). All much much bigger than Wuxi. Wuxi was once pretty important, but it lost its importance when the tin production ran out. It literally means "No tin anymore". People see it is neat small garden city. Wuxi itself is very small, but has two bigger satellite cities outside, Yixing (>1mil) and Jiangyin (>1mil).

Compared to Shuzhou and its other neighbors it's tiny. Small city is ok.
