Yesterday I told you the obituary of Mr Yu Min, to whom no matter how high we praise to the skies on the archievement and contribution he rendered would never be enough.  Today I would like to introduce another praiseworthy task done by Mr Chen Kaijia, the commander-in-chief of China nuclear bomb blasts, at:

What did Mr Yu and Mr Chen have in common during their odyssey to success?  Certainly, it had been perspiartion and insperation combined.  But they must have made a huge sacrifice: their families.  Both of them had led an incognito life for over thirty years, and it seemed they had totally disappeared from the world, including from their families.  What was the incentive that motivated them to do such a sacrifice.  Nothing but the belief of "為有犧牲多壯志 敢教日月換新天" from Chairman Mao. 

P.S. You may ask what hell both Yu and Chen did, along with many a highly meritorious scientists, had anything to do with Taiwan?  Yes, they had.  At least you have not seen any American soldier boys holding Taiwanese bar girls and swaggering along the streets in Taipei since China Mainland accomplished her "Two Bombs and One Missile" project in late 60s and early 70s.
