The Red Hair State was once allowed to trade with China. When the border marshal saw that a band of them, he declined the entrance permission; therefore, those red-haired individuals implored the marshal to allow as many as a carpet could hold. The marshal thought a carpet could only be for a few persons, so he granted. The red-haired person then laid the carpet on the shore, which could accommodate only two people. However, stretching out the carpet further allowed four to five people to sit. They kept on pulling, and more and more people stepped on. Instantly, the carpet extended so long that it could allow hundreds of them to go ashore. Then they all extracted daggers. Off China guard, the red-haired plundered a wide sphere of several miles before they left.
