Livestreaming(直播) is turning out to be quite a big trend. From playing video games to dancing to K-pop, streamers are making big money simply by sharing their daily lives with the world. Some streamers even become world-famous, especially e-sports players like Shroud and Ninja.
I don’t really watch a lot of livestreams. When it comes to gaming, I’d rather play video games myself than watch someone else play them. But I understand that some gamers might watch them to pick up playing tips.
Sometimes livestreaming is a bit vain. A lot of streamers are just doing it for the attention. That being said, I’ve also found some good streams. For example, one streamer I used to watch would hang a sign around her neck that asked for tips. When her tips reached a certain amount, she would put a metal bowl on her head and hit it with a wooden spoon. It was weird(怪异的),but I just couldn’t stop watching sometimes. I’d never seen anything quite like it before.
Other streams can show us things that we wouldn’t usually get to see. Since you can start your own livestream with just a smartphone, even people in the countryside can show us their lives. I’ve seen parts of rural(农村的) China that I would never normally see by checking out their streams. It gives me a look at a lifestyle that I’m not very familiar with.

Faster fifth generation
If you look at the top of your phone, you’ll usually see a little symbol that says 3G or 4G. The “G” stands for the “generation(代)” of your mobile network. But these symbols will become things of the past after 5G networks fully arrive.
On march 30, Shanghai vice-mayor(副市长) Wu Qing made the first 5G video call on a Huawei Mate X smartphone, CGTN reported. Shanghai has also become the first city in China to start testing 5G networks.
About 100 times faster than 4G networks, 5G will let people download and upload data faster than ever before. But 5G won’t just bring faster mobile Internet. People can use it for many other things as well.
For example, 5G will help to make self-driving cars safer. Today’s self-driving test cars have one problem-lag. When the car “sees” an obstacle(障碍物), it sends this information to a data center and receives instructions.
However, it takes time to send and receive this information. With this kind of lag, the cars might crash because they don’t receive instructions in time. With 5G, this lag will be greatly lowered, making the cars safer, according to CNN. 5G could also be used to power the Internet of thing(IoT, 物联网). This refers to a large online network that connects all things and people. Fast Internet speeds will be the key to developing this technology.
The IoT could be used in a lot of ways. For example, with IoT, your refrigerator could automatically(自动地) place an order online for eggs when it finds that there are no eggs left inside.
Who is building the network?
