Why are there no towers on Cloud Terrace at Juyongguan Great Wall of China-Annieli tours

Annieli tours’s Beijing Tour Guide answer:
Luban’s sister said, “You can build the Cloud Terrace at Juyongguan Great Wall of China, Stop bragging!” Luban knew his sister didn't believe him, but he didn't mind. His sister said, “If you can finish the Cloud Terrace in one night, I can make three pairs of shoes in one night.” Luban said, “OK, That is a bargain!” Luban finished three towers on the riverbank soon and began to build a bridge in order to move the towers to Cloud Terrace. At this moment his sister just made two pairs of shoes. Day was breaking, they failed to accomplish the purpose. From then on the three towers were left on the riverbank and there was no anything on the Cloud Terrace.

3rd art of the Origin of “the First Pass under Heaven” is over.
