Well, although I am retired now, I still have to learn what I should learn. For example, if you buy it online, you can't. Sometimes you forget to bring money when you go out. You have to pay by WeChat or Alipay. You must learn these things that must adapt to the party, otherwise it will be very inconvenient for your future life. So although I am old, I still have to learn what I should learn. I will call you patiently. You have to learn more in the future, and it will be very inconvenient to go out to do business in the future.
