Recently, mobile payment has completely taken over our lives, and what we use for traveling is basically no longer paper money. Go out to buy things, open WeChat or Alipay sweep to pay, fast and convenient. Especially in the past few years, I clearly feel the mobile payment to bring us the amount of change. Before, we had to carry a lot of cash when we went out to buy things, which led to the possibility that our money would be stolen or lost on the way to buy things. Now we have mobile payment, we only need to have a cell phone in hand, we can complete the payment, our life has been changed by electronic money.

There are many other things besides e-currency that have changed our lives, such as the emergence of cell phones. In the past, when we didn't have cell phones we contacted other people by writing letters or helping to carry messages, but now with cell phones, we can call directly if we need to tell others anything, which is very convenient and time-saving. Cell phones also allow us to learn about the world's affairs without going out, and the changes that cell phones have brought us are huge.

Changing our lives is also the automobile. Previously, it was very inconvenient for us to go out of town or to do something. But now we have a car, we travel very convenient, only a short time we can reach the place we want to go, but also can meet the people want to see. The emergence of automobiles has greatly facilitated people's traveling, and we can go to many places with automobiles. And now that cars are becoming more and more popular, our lives are becoming more and more convenient.

Our life now is really a great change, I like this change, the power of science and technology is infinite.
