一段旋律可以永远陪伴你。

I have to say to myself that some birds aren't very close. Their feathers are just too bright. When they fly away, you know it's a sin to lock them up, and you'll be inspired by them. Still, the place you live in is that much more drab and empty that they're gone. I think I really miss my friends.

所以，储备是国家最重要的事；粮食是国家的宝物；武器是国家的利爪；城池是守卫国家的屏障。
