顺势而为， To go with the flow。 孙子说，在山地行军，要选择在有水草的地方走，要选择在高的、向阳的地方停留，不要从上往下攻打敌人。也就是说什么样的环境就要有什么样的行军策略。 Sun Tzu said that when marching in the mountains, one should walk where there is high grass(to hide), stop at high and sunny place, and never attack the enemy from a lower position to a higher one. In other words, one’s marching strategy must match the environment. 举一个生活中的例子，在中国北方的农村，春天适合播种，就应该去播种，冬天适合休息，就应该在家里休息，如果出去播种，也不会有什么收获。 Here’s a life example: in rural northern China, spring is the right time for sowing, so people sow seeds then; winter is for resting, so they stay at home. If you go out to sow seeds in winter, you will get no harvest at all. 所以说，做事是顺着形势，找对时机不用费很多力气，事情也能够做好。 So when you do things, follow the flow of events and seize the right moment—you won’t have to struggle hard, and you’ll still get things done well.
