If you stop a random person on the street in China, there’s a pretty good chance their surname 【小题1】 (be) either Wang, Li, Zhang, Liu or Chen. That’s 【小题2】 those are the five most common surnames in China — shared by 30% of the population. And the vast majority of the population share just 100 of those surnames. 【小题3】 (put) that in perspective, the United States reported 6. 3 million surnames in its 2010 census.

There are a few reasons for this: China is less 【小题4】 (racial) diverse than countries such as the US, where a wealth of minority groups increase surname diversity. It also has to do 【小题5】 language; you can’t just add a random stroke to a Chinese character and create a new surname.

But there’s also another factor at play: technology. With China 【小题6】 (roar) into the digital age, nearly everything has moved online—from making appointments to buying train tickets. The main problem is that not all Chinese characters 【小题7】 (code) into computer systems. That meant 【小题8】 world of trouble if you happened to have a rare character in your name. As of 2017, up to 60 million Chinese citizens faced this predicament, according to Xinhua.

People with rare characters in their names, 【小题9】aren’t compatible with existing computer systems, can get left behind — pushing many to change their names for the sake of 【小题10】(convenient), even if it means abandoning centuries of heritage and language.

To try to address this, experts have increased the database from 32, 000 characters to 70, 000 characters, according to the government. They’re still working to expand it to include more than 90, 000 characters, said Chen Jiawei, an associate professor at Beijing Normal University.

It is a knowledge system and social practice【小题4】(form) through people’s observations of the Sun’s annual movements and its influence on the climate.

The 24 Solar Terms came into being during the Qin and Han dynasties. At that time, most Chinese people made their living on farms, so weather changes were【小题5】(extreme) important. However, they had no satellites, Internet or weather broadcast【小题6】(help) them.

But people found a way. They studied the Sun’s movements with a sundial (日冕仪). They also paid attention to other【小题7】(nature) changes such as temperature, water and crops【小题8】(grow). In the end, they worked【小题9】the 24 Solar Terms to mark the changes.

The terms became their guide to work. For example, Awakening of Insects (惊蛰) is when insects wake up from a long sleep in the cold winter. Farmers take it as a sign of warm weather and get busy【小题10】(farm).
