Antonio López de Santa Anna，a former president of Mexico，was living in New York in the late 1860s. While he was there，he met with Thomas Adams，an inventor. Santa Anna shared with Adams his idea for an invention—a new process，really，for making rubber（橡胶） products such as tires（轮胎）. 

▲Santa Anna thought it would be possible to blend the rubber with chicle（糖胶树胶），the milky juice of a tropical（热带的） tree. That would make rubber products much cheaper to produce. Adams told Santa Anna that he was willing to try. Later，Santa Anna prepared one ton of chicle to be shipped to Adams from Mexico. 

Adams worked for about a year，trying different blends of rubber and chicle. None of them were successful. The inventor still had lots of chicle left over and wondered what to do with it. Then he remembered Santa Anna's stories of people chewing chicle in Mexico. So Adams made a small number of chewing gum（口香糖），packaged it，and sold it in local stores. The gum was much tastier than other American gum，which was made from wax（蜡） or tree sap（汁）. 

Although Adams's original idea was a failure, chewing gum was a success. In 1871，he invented a machine to produce gum so he wouldn't have to make it by hand. Adams enjoyed success for the rest of his life，and people have enjoyed all kinds of tasty gum for years. 

Dong Yuhui, a 30-year-old livestreaming host for East Buy(东方甄选), found himself in an online controversy(争议) that began on Dec. 5. 

East Buy, a subsidiary of the New Oriental education, said that many of the things Dong said in his livestreams were written by the East Buy team, not by himself. The then-CEO, Sun Dongxu, criticized Dong and the team, which made Dong's fans upset. 

Surprisingly, this controversy made Dong even more popular. In just one week, his Douyin followers increased by over 3 million, while East Buy lost more than 2 million followers. Sun was no longer the CEO, and Dong became vice president of New Oriental's cultural and tourism business.

Despite his rising fame, Dong remains humble. " I am not good-looking or tall;I don't know why I have so many supporters, "he said. 

However, Xu Hanze, an associate professor(副教授) at Nanjing University of Aeronautics and Astronauts, believes that Dong got more attention because of his talent and intelligence, thanks to his habit of reading extensively. 

In the age of consumerism, Dong does not trick consumers into buying unnecessary products, but encourages them to be rational(理智的) when shopping online. He also puts more effort into educational activities and events to help farmers. 

He believes that people should not wish to be the next Dong Yuhui. " I want to tell other young livestreamers that they do not need to be me, as each story is moving in its own way. "

He went on to say that people are not products made on manufacturing lines, and that diversitv(不同) what makes people special.
