15-year-old girl Yang Qisen scored 691 in this year’s college entrance exam and has been admitted by Tsinghua University, one of China’s top universities.

“I am always the youngest in my class,” Yang Qisen told Chongqing Evening Daily. “My daughter entered primary school when she was just four years old,” said Yang Qisen’s mother. “Then she often wetted her pants because she was too young.”

“I am seldom worried about her study for she has strong self-discipline,” her mother said, adding that her daughter is independent and often takes care of her younger brother.

Yang doesn’t regard herself as hard-worker. “Hardworking is another kind of laziness” is her motto. “I don’t like immersing myself in studying, and prefer effective study,” she said. More self-discipline and deeper thinking is key to her success.
