China is running ahead in 5G . In March, 2019, the Shanghai Hongqiao Railway Station became world's first "5G railway station". Now, it takes only 20 seconds to download a long movie there.

We are moving closer and closer to the 5G world. However, the new technology is still strange to most of us. What is 5G, after all? At first, 5G is fast. 5G will be much faster than today's 4G networks!

The first 5G modem（猫，调制解调器）of the IT company Qualcomm supports speeds of up to 5 Gigabytes（千兆字节）per second. Most of us have never experienced anything close to that speed. And we are only talking about the first generation（一代）of 5G modems, Future models are likely to be even faster.

But 5G is not all about speed. Have you ever been to a large event where your data (数据)connection slowed down? That is because 4G networks can only support a certain number of devices(设置) per square meter. 5G networks will be able to do much better.

Now, you begin to understand why 5G is a huge change over 4G. The technology is not Just for the smartphones. It has a strong influence(影响) on every connected device. With 5G, self-driving cars will be able to communicate with the world around them as quickly as possible. Wearables, Pcs and smart home devices will be able to improve as well.

The year 2019 marked the 40th anniversary of the start of diplomatic (外交) relations between China and the United States. When the Joint Communique on the Establishment of Diplomatic Relations《中美建交公报》went into effect on Jan 1, 1979, the two countries began a friendship that stays deep to this day. Whether it's stepped-up trade, shared entertainment markets (娱乐市场) or simply people-to-people exchanges, China and the US have helped each other grow and succeed.

Trade and economy (经济)

As the largest and second-largest economies in the world, the US and China have a strong economic relationship. They are both major trade partners for each other, exporting (出口) and importing (进口) billions of dollars worth of goods every year. As of October 2019, the total value of trade between both countries was nearly $468 billion (3.26 trillion yuan), according to US Census Bureau. Certain US products, such as high-end (高端) clothing and electronics brands (品牌), are in high demand (需求) in China. Likewise, China exports large amounts of manufactured (制造的) goods to the US, including clothing and industrial equipment (工业设备).

Entertainment

As the world's fastest-growing film market, China is Hollywood's top target (目标) at the moment, with new releases in China earning millions of dollars. Avengers: Endgame 《复仇者联盟4：终局之战》 for example, earned $614 million (4.28 billion yuan) in China last year, according to Box Office Mojo. China, for its own part, is working to develop its own movie industry and send its films abroad. The sci-fi film The Wandering Earth 《流浪地球》, which came out last year, did quite well in the US. It became China's third highest-grossing (票房最高的) film of all time with total worldwide earnings of nearly $700 million (4.88 billion yuan), according to Box Office Mojo.

People-to-people exchanges

The US is a top choice for many Chinese students who wish to study abroad. US universities have welcomed record numbers of Chinese students in recent years, with the total number of students reaching 360,000 as of June 2019, according to the BBC. This has allowed students from both countries to gain a greater understanding of each other's cultures. And, of course, there are those on both sides who choose to live and work in each other's countries. Many Chinese researchers work in US labs (实验室), while in China, there are many US citizens working in fields ranging (范围) from journalism (新闻) to English education.
