spring, a candy-coated haws stand caught his attention. Having never tasted a candy-coated haw, he immediately went up to buy one.
However, the vendor shook her head when seeing the 100-yuan note Jim handed over to her. She had no change! How disappointed Jim was! He was about to quit when I took out my cellphone, scanned the QR code on the stand and paid the vendor 5 yuan.
Jim was surprised at what I had done. Then I explained to him that nowadays in China QR codes were everywhere, and we could pay with a cellphone for almost everything. “Wow!” Jim said, “The candy-coated haw tastes great, and the payment method seems even greater!”
