科学的力量在于它的普遍性和无私性，它超越了国界和文化的限制。
The power of science lies in its universality and selflessness, transcending the boundaries of nations and cultures.
The secret of change is to focus all of your energy, not on fighting the old, but on building the new.

这个人生阶段，这小小的阶段是“幸福来敲门”。
【译文】 粮食尽量精，肉类尽量细。变质的东西不吃；变色的东西不吃，变味的东西不吃；烹饪得不好不吃；不是吃饭的时间不吃；切的不好看不吃；调味品不好不吃。肉类虽多，但不要吃过量。只有酒不限量，但不要喝醉。从集市上买来的酒肉不吃；每餐必有姜，但不多吃。
