生活中，会有各种各样的责任和重担，压在我们的肩上，就算我们竭尽全力，也不能把所有的问题，全都一肩扛，就像你的手掌再大，也无法抓紧一把沙，无论你多么的用力，总会有沙粒从我的手心离去。
In life, there will be all kinds of responsibilities and responsibilities on our shoulders, even if we do our best, we can not carry all the problems, just like your palm, no matter how big, you can not grasp a handful of sand, no matter how hard you push, there will always be sand out of my hand.
