       The famous Chinese mathematician(数学家) Hua Luogeng was born in Jintan County, Jiangsu

province in 1910. When he was young, life was very difficult for his family. Still, the boy took great

interest in maths. In the summer of 1931, he was fortunate(幸运的) enough to become an assistant

in the Math Department(系)  of  Qinghua University,  where he spent every moment he could find

working and studying,  and he finished his compulsory(必修的) math course all by himself in only

13 months! Between the years of 1936 and 1938, he was further studying in Cambridge University

in the U.K. In 1950, together with his family, he returned to China from the USA. He said,  "I'm

Chinese, and I'll do my best for my motherland." So he did. He devoted(贡献) all his life to the

math study and won the great fame(荣誉) for our country. He died for heart trouble in 1985 while

lecturing in Japan. People will always remember him as a great scientist.
