Dear George，
I am glad to hear that you came to China ten years ago and will travel to China this winter vacation. You want to understand the changes that have taken place in China over the past decade in terms of communication methods, shopping payments and transportation. I'd be more than happy to introduce you to these.
First of all, in terms of communication methods, We have gone from the old flip phone to the current touch-screen phone, and even R&D out 5g of communication technology. This makes us a lot more convenient in communication. Secondly, in terms of shopping payment, our Alipay and WeChat payment have gained a lot achievements。Now we don't need to bring cash when we go out, just bring a mobile phone is enough. Choose what you want to buy then you can pay by brushing the payment code. This really makes our travel a lot easier. This new type of payment channel can avoid the loss of our cash and the inconvenience of carrying our wallet. And then in terms of transportation, Our city has installed shared bicycles. We don't need to take a bus outside at this time. This will not only allow us to travel environmentally, reduce carbon dioxide emissions, but also help us keep fit.
China's economy has developed rapidly this decade and the people's living standards have been continuously improved. As a native of China, I feel this change deeply. And I'm proud that I was born in this country.
