I never need to carry cash. Shared bikes are also easy to find and cheap to ride. Last week, I ordered noodles through an app. The food arrived in 20 minutes and was still hot. I really enjoy this digital life. However, when I visited my grandpa in the countryside, there was no QR code in the small shop. I had to walk home to get cash. That made me realise how lucky we are to live in a place with good technology. I look forward to even more convenient inventions in the future. 1 学科网（北京）股份有限公司 $
