Hangzhou West Lake has three wonderful "broken bridges, lonely mountains are not alone, long bridges are not long". I have been to the West Lake many times. Sometimes I can't figure out where it is when I walk, because the surroundings are picturesque. This time I went to Leifeng Tower and took a bus to the "Changqiao" station. The long bridge, also known as the double-cast bridge, has a sad story.
