Living in China has made me realize how convenient life can be. It's much better than I ever thought.
The moment I came to this country, a wave of pleasant surprise washed over me. The public transport system, especially in its big cities like Beijing and Shanghai, is great. The subway networks cover every part of the big cities. People can avoid the traffic jams and get to where they want to go much faster. High-speed trains that connect cities like Beijing and Shanghai in less than five hours are another example of China's wonderful transportation system.
Another great thing that stands out in China is the availability(可用性) of services. If my bike is broken and needs a repairman, or if I want to have daily needs, electronics or even medicine, I just need to make a phone call or click on my phone a few times. Since everything is available online, I no longer have to go far to the supermarket or the store.
It is one of the key reasons why I've stayed in China for so long—something I've never experienced in any other country.

What’s more, China’s convenience doesn’t only lie in the speed of services, but also in their user-friendliness. The whole system is designed with user experience in mind. For example, the apps I use for transportation or deliveries are user-friendly, even for people who are not good at technology. Everything, including payment methods, is simple and direct. It means you don’t need to spend time learning how to use the systems. This makes it easy for everyone to get things done without difficulties.
The convenience in China has made me more productive and relaxed. I’m sure that with technological progress and infrastructure development, life in China will become even more convenient in the future.
