杨振宁 is correct that he“总是能在关键时刻做出正确选择”. Judging from the choices he made, he is clearly smarter than 萧光琰 and 姚桐斌. No wonder he won the Noble prize while the others didn't. I don't see how you can call anyone making the right choices for himself 卑鄙. The very problem of culture revolation is trying to make people not self-interested. The result? - just look at today's China.
