嗯，我觉得蛮需要的。因为学了农以后呢我可以看到这个桔子是怎么长出来的，然后也就知道这个桔子装箱怎么样，怎么去采摘，其实以前没看到过不知道，以为很简单，只要摘下来然后包装就行，其实没有那么简单，很多很细小的地方还是需要你亲手去尝试的，才能感觉得到，所以，至少我觉得可以感受一下那种“粒粒皆辛苦”这种感觉。

Uh-huh, I think it's quite necessary. Because after studying about agriculture I could see where a tangerine came from, and could see how they were packed, how to pick them. Actually, I had never seen that before, so I didn't know. I thought it was very simple--just pick them, package them and that's it. But actually, it's not that easy. There are a lot of very fine matters that you need to go and experience for yourself, in order to be able to understand. So, at least, I think I experienced, for a while, the feeling behind the saying: ``Every single grain is the fruit of hard work."
