楊振寧 is correct that he“總是能在關鍵時刻做出正確選擇”. Judging from the choices he made, he is clearly smarter than 蕭光琰 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.
