“I feel great!” said Wang Yaping when she came out of the Tiangong space station, waving back to Earth.

On Nov. 7, the 41-year-old made history. She became China’s first woman space-walker! Wang, together with astronaut (宇航员) Zhai Zhigang did a 6.5-hour spacewalk. Since 1984, only 16 women(including Wang) around the world have ever done spacewalks, according to Global Times. But woman space-walkers are very important to space. “Humans may live on other planets someday. If we don’t let women take part in this, we can’t prepare well. We need to study how women’s bodies change in space. That’s why Wang’s spacewalk is important,” a scientist told Global Times.

Women are more patient and careful. Women can better deal with loneliness. Women have better skills to talk with others. It’s easier for women’s hearts to work well in the environment without gravity. So it’s easier for them to stay longer in space.

China is a world leader in 5G network quality and has already built over 1.6 million 5G base stations. This means that China’s telecom companies will be able to offer 5G networks for mobile phone users.

Each mobile network generation is faster and more powerful than the one before it. 1G let us talk to each other. 2G let us send messages. 3G gave us data and the Internet. And 4G made all of these things faster. What`s special about 5G? 5G has a very short delay（延迟）between sending and receiving information. Now, 4G takes about 100 to 200 milliseconds to send and receive data. But 5G will get it down to 1 millisecond or less—this is almost real-time.

This big change will not only make our mobile Internet faster, but also deeply change our lives. Read on to find out how.

5G + entertainment 5G networks are about 100 times faster than 4G. This means you can download a movie in seconds using 5G. Also, virtual reality（VR）games will become more popular with 5G. The short delay of 5G will make the games feel even more real. 5G + transport 5G will also bring us safer self-driving cars. These cars can send signals to each other. They also talk to traffic lights and road sensors. 5G will allow cars to react（反应）even faster than human drivers. 5G + smart homes 5G also makes the Internet of things possible. Internet of things is a large network that connects everything to the Internet. Smart homes are part of it. For example, the oven can automatically（自动地）start making breakfast after your alarm rings. And if the smart sprinkler feels the air becoming dry, it could water your plants by itself.
