However, I've had some digital problems here. Today, I wanted to get some vegetables and meat from a shop. I decided to ride a shared bike to get there. But it took forever to find a bike! I finally found an old one. But that 20-minute ride cost me an arm and a leg - 4.8 pounds! In the shop, I quickly got everything I needed. I wanted to pay with my smartphone. I asked the shopkeeper to show the QR code, but she didn't understand! Next, I tried to use my digital wallet, but the shop's payment system didn’t work. The shopkeeper told me to use cash. As I always make digital payments in China, I never carry my wallet. I had to go home to get some cash. When I got home,I was so tired that I gave up on cooking. I ordered my favourite dishes through an app instead,but the delivery was really slow. When my dishes finally arrived 90 minutes later, they were stone-cold! I had to heat them one by one in the oven. I felt tired and hungry. Except for today, I’ve had a great holiday. However, I’m looking forward to going back to China.
