Across the Yangtze river from my hotel in Wuhan there was one of the four great towers of China, The Yellow Crane Tower. It was only a 3 km walk, most of which was across the first Wuhan bridge over the Yangtze river. The mile long bridge was built in 1957 after the Chinese civil war. It was built as a memorial to the success of the new democratic revolution.
The current Yellow Crane tower was built in 1981. It was first built in 223 AD, but was destroyed and rebuilt several times by wars and fires.
