North by Northwest

I used to take it for granted that the train from Hangzhou to Beijing went due north, while actually it goes north by northwest, and the route is quite roundabout at some stretches.

Obviously the shortest way is the beeline, but the shortest is not always the best. Along the beeline between Beijing and Hangzhou, there are countless small villages where transportation is not easy. And there are also a vast expanse of hilly areas and marshlands where transportation is utterly inaccessible.

Therefore, we make a detour. The roundabout rout stretches to six big cities and avoids many impassible areas. This detour is certainly better than the beeline, as how easily you reach your destination depends not only on the distance of the route, but also on its resistance.

In fact we can apply the strategy of “north by northwest” to our studies. We students should do anything necessary in learning even if it seems to be a diversion
