Last weekend, my British friend, Jim, spotted paper-cutting stand when we were wandering on the street. Had never seen paper-cuts, he immediately bought one. Therefore, the seller shook her head at the moment she saw the 100-yuan note Jim handed over to her. She had no changes! How disappointed Jim was! He was about to quit while I took out my cellphone, scan the QR code on the stand and paid five yuan. Jim was very surprising. I explained to her that nowadays we could pay with a cellphone for almost everything. “Wow! ” Jim said, “The paper-cut looks great, and the payment method seems even great!”
