阅读下面的短文，然后按照要求写一篇150词左右的英语短文。

It is reported that two 66-year-old men graduated this summer from Sun Yat-sen University, a well-known university in Guangzhou.

Li Yiquan, a Chinese-Singaporean, earned a postgraduate(研究生) degree in software engineering, while Ang Toon Aun, a Chinese-Malaysian, earned a bachelor's degree with a major in Chinese as a foreign language.

Li, a retired engineer, now lives in Hong Kong. His daughter also received a postgraduate degree this year, but from a British university. So she participated in his graduation ceremony in Guangzhou. Li said he had a special feeling for Sun Yat-sen University because his parents and brother graduated from there.

It wasn't easy for Li to return to school while in his 60s, he said. He failed math exams several times after beginning classes, even though he had a good foundation in math; he graduated from Hong Kong Baptist University majoring in physics 40 years ago and worked as an engineer before retiring.

Ang Toon Aun, 66, was tired of his business career, so he decided to study Chinese at the university and passed level 9, the highest level of the Chinese Test.

"There's nothing in the world that makes me happier than study," said Aun. Many old people in Malaysia were encouraged to keep studying after retirement, but few of them chose to study on campus for a degree as he did.
