我一直想完整地走一遍，体会一下你爷爷当年吃过的苦。你爷爷以前常跟我说他和战友们一起爬雪山，过草地，吃树皮的故事，那种艰苦我们是难以想象得到的！

I've always wanted to walk it all the way, and experience the bitterness that your Grandfather tasted during those years. Your grandfather often used to tell me about climbing snowy mountains, crossing grassy fields, and eating bark with his war-time buddies. It's hard for us to imagine that kind of bitter struggle.
