Nowadays, phone calls and messages help us get in touch with others. It means that we seldom write letters now. But a TV show, Letters Alive (《见字如面》), is bringing back this old habit.

Letters Alive invites famous actors and actresses, but there are no funny jokes or competitions. It’s just one person walking up to a microphone (麦克风) and reading a letter. The letters were written by people from different times in history. For example, in one period, they read a letter written by famous writer Xiao Hong to her younger brother in 1941. The letter shows that Xiao Hong missed her brother so much and had great hopes for his future.

“Every letter opens another world for us,” according to Guan Zhengwen, the director of the TV show. “We can also touch the heart of the writers’.” Since its first period on Dec. 5, Letters Alive has been widely praised. Many audiences said that it had provided a kind of fresh air to today’s TV shows.

Besides Letters Alive, some other cultural TV shows have also been well received by Chinese audiences. Chinese Poetry Conference (《中华诗词大会》) is a traditional Chinese poetry competition. And Readers invites people to read poems and articles they like or wrote. It shows that cultural values and true feelings are becoming our interest.

If you look at the top of your phone, you will usually see a little symbol that says 3G or 4G. The G means “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 well. For example, 5G will help to make self-driving cars safer. Today’s self-driving test cars have one problem—lag (延迟). When the car “sees” something, 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 improve the Internet of Things (IoT物联网). This means 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 fridge could place an order online for eggs when it finds that there are no eggs left inside.
