What's the joke about Bajiaojing Street in Fuling?

Bajiaojing is located in Wuyangshu Street, Fuling District, Chongqing. In the past, the wellhead of Bajiaojing was an octagon, from which the name of Bajiaojing originated. Now that street is called Bajiaojing.

in recent ten years, due to the repair of ladders, the ground has been raised, and the wellhead has to be re-made. People can't make the octagon, so they have to make a round wellhead casually. Later, for safety, a railing was made next to the octagonal well.
