I enjoy swimming very much. I started to learn to swim when I was 12 years old.
To be better at it, I practice swimming twice a week. I usually swim for at least two hours each time.
Even though swimming can sometimes be boring, I still want to keep going. In
the future, I want to take part in swimming matches.

Beidou is China’s own navigation system. It took us 20 years of hard work to make it. It is safer for us to use and helpful in many ways. We can use it to know where we are and send texts when there is no phone signal or internet. Farmers can also use it to make farming smarter. More than a system, Beidou also shows that China is a strong country in science and technology.
