A pair of twin brothers Chen Dingyi and Chen Hongyi from Zhumadian, Central China's Henan province, received the acceptance letter from Peking University and Tsinghua University, commonly believed to be China's top two universities, on Friday.

Dingyi, the elder brother, is only nine-minute older than Hongyi. In this year's gaokao, China's college entrance examination, Hongyi's grade was three points higher than Dingyi.

"Dingyi is a well-behaved student with good grades, and he loves reading, listening to music and travelling in his spare time," Cai Zhiqiang, his head teacher said. Dingyi studies hard and is always willing to help others.

"Hongyi had a clear plan for life when he entered high school. He has a meticulous learning attitude and a strong thirst for knowledge. And he is always eager to explore something new," said Zhai Changhai, Hongyi's head teacher.

The twins' parents are both teachers. When asked about the experience of raising their sons, the mother said, "We focused on developing their learning habits. As they have good habits, their grades will go up. And I think students shouldn't spend all day studying; they need time to relax."

"We should consider every day lost on which we have not danced at least once," the line of Friedrich Nietzsche's is the twins' favorite motto. Talking about their future plan, the twins said they will study harder at university, and contribute to China's scientific research field.
