My dear country, I can not find words to express your love, you are so great, you are so strong, we have the crook of the arm of your sturdy, happy growth.

我亲爱的国家，我无法用言语来表达你的爱，你这么大，你是如此强大，我们有您的坚固，快乐成长的臂弯。

Nope, these are movies that tackle big questions like: what does it mean to be happy? How do we express love? How do we think about our responsibility for other people's happiness?

不，它们是针对大问题的电影。例如：快乐的含义是什么？我们如何表达爱？我们如何看待对别人快乐的责任？
