I still remember the countenace of a HS teacher when he told us in the classroom some time in late 1964 or early 1965 that China had succeeded in exploding her first A-bomb.  The teacher, who then risked his being charged with the crime of "propagating for communist bandits", recounted the news with a mixture of excitement and pride; but most of the students showed no sign of similar sentiments of that kind, and I guess they must have doubted how could it be that China was capable of entering that high-leveled A-bomb club. 

Not until recently did I know Mr.Zheng Jiaxian(鄭稼先) is one of the most important pioneers in developing China's A-bomb and H-bomb, with which China has withstood the so-called nuclear bluff from America and Soviet again and again, and now safeguarded her peaceful rising.  Mr.Zheng died yesterday 30 years ago at only 63. (What a terrible shame it was!)  Attached below is a brief biography and some memorial interviews given to Mr.Zheng, the great scientist and patriot.

P.S. Two years later after Mr.Zheng's decease, a colonel betrayed Taiwan's secret nuclear project to America.  To late President Chiang Ching-kuo and the majority of islanders the project had been fell short of success for lack of a final effort, but to me it was just part of the evil scheme of their trying to seek Dutai or Taidu.
