Shanghai Vice-Mayor Wu Qing made the world’s first 5G video call on March 30, 2019, in Hongkou, Shanghai.
Now 5G, fifth-generation mobile communication technology, is coming. Compared with 2G, 3G, and 4G, 5G is not independent and brand-new. It is further development of present mobile communication technology (移动通信技术).
5G makes information break through the limitation of time and space, providing a more wonderful user experience. It will influence (影响) all areas of the society in the future, such as industrial machines, farming equipment, transportation and so on. It’s much faster than 4G—the 5G mobile network is more than one hundred times faster than the 4G mobile network. It will also realize the general hope of “Get the information whenever you want and all things on earth are at your fingertips”.
In recent years, China has paid great attention to the use of 5G and made great efforts to develop 5G network. China is expected (预料,预期) to become the world’s largest 5G market by 2025 with 460 million users, China Daily reported. The user number in China is expected to be higher than that of Europe (205 million) and the United States (187 million) combined (总和的). Backed by 5G, China’s mobile ecosystem (生态系统) is expected to add 6 trillion yuan (about 895.92 billion U.S. dollars) in value to the national economy (经济) in 2023, up from 5.2 trillion yuan last year, said the GSMA report.

Have you ever dreamed about sending a letter to yourself or your friends in the future? While express mail (快递) is a fast way to send your letters, there is another type of mail appearing in China as a new business—future mail.
“The letter should be sent next Mother’s Day and not a day earlier!” Lin Xiaofan, a college student in Shanghai, tells one of the companies offering the service.
Lin Xiaofan wrote the letter to her mother nearly a year earlier to express her love to her mother for next Mother’s Day.
“Offering this service makes people slow down and lets them understand the meaning of ‘time’ in another way,” said Zheng Zhimin, manager at a “future mail” company. Zheng thinks “future mail” letters help remind us of care, friendship and love.
While “future mail” is becoming more and more popular, some people are wondering what will happen if the postal address changes or if the company goes broken before the letters arrive.
Zheng said customers are glad to sign a contract (签订合同) to make sure that they can be compensated if their letters are lost or damaged.
Most of the customers are college students and young white-collar (白领) workers. Psychologists (心理学家) said that young Chinese might have a new way to express their feelings through this service. Most people put their hopes and wishes in the letter so that they can experience the connection (联系) between the past and the present when they receive the letter.
