I just spent about 6 weeks in Wuhan and am about to spend about 3 more. There are some nice restaurants, a very nice park next to the lake, and some other sites to see (Yellow Crane Tower, Guiyuan Temple, etc.) So if you are going to be there, there are some things to see and do.

But in general, I would suspect that there are similar parks, temples, etc, in Beijing or the other cities you will be visiting. If it were me, if it costs you much money, I wouldn't stop in Wuhan, but if you can do it without costing much, there are some things to see and do.
