In ancient times, the word "beam" not only had the meaning of bridge, but also the meaning of river bank and cofferdam. Kaifeng City, located on the ancient Yellow River Road, was known as the "girder" in history. It is so called not because there is a bridge here, but because there are many large low dams and weirs there, which can be used for fishing to satisfy people's appetite.
