How Did Yuan Longping Revolutionize China’s Rice Production?
①Yuan Longping was born in 1930 in Hubei. As a child, he was very interested in plants and other living things. He grew up to be a curious and hard-working plant scientist. Yuan wanted to solve the problem of food shortages, so he began conducting experiments to improve rice yields per hectare (10,000 m2).
②Plants come in many different varieties; for example, some types of rice have long grains, while others have short grains. For centuries, people have been crossing different plant varieties to create hybrids. Such plants proved to have desirable qualities from both parents. Yuan believed that it was possible to do the same with rice. He tried different ways of creating rice hybrids, only to discover that his attempts were unsuccessful.
③Even though it often seemed too difficult to complete this task, Yuan didn’t give up. After many years of hard work, his experiments finally bore fruit. This was a major discovery since no one had previously been able to cross two different kinds of rice. It had a huge impact: the first hybrid rice variety increased China’s rice production by 100 million tonnes in little over a decade.
④Yuan didn’t stop there — instead, he continued experimenting and created super hybrid rice with yields over 15 tonnes of rice per hectare. Thanks to Yuan’s work, China became self-sufficient in rice. Our country continued to increase its rice yields to become one of the biggest food donors in the world. In 2019, he received the Medal of the Republic for his outstanding contributions. At the age of 90, Yuan Longping still hasn’t retired. With a growing global population, the world needs to produce enough food to feed everyone, and Yuan is working to make this happen.

3 . But Disney’s story actually started two decades earlier with what Walt Disney called "Daddy’s Day". On Saturdays in the 1930s and 1940s, Disney would take his two daughters to ride the Griffith Park merry-go-round, which they’d enjoy while he sat on a bench dreaming of ways for families to have fun together. Disney disliked the amusement parks they often visited, seeing them as dirty, unimaginative places run by rude employees.
Disneyland opened then. The 5,000 expected guests increased to 28,154, thanks to fake tickets. After the madness of opening day, Disney and his new park were criticized in the press. The media predicted a quick and early end. But the public didn’t listen. Visitors arrived in large groups, and within weeks Disneyland was a success.
Over sixty years later, Disneyland’s popularity continues to grow, with total overall attendance topping 700 million and showing no signs of slowing down.
