This is a must watch. It is an advertisement, supposedly, based on a true story. I almost cried when I watched it. I hope I will have the courage, and the guts like the men in the video when I reached the final stage of my journey on Earth. So much to be said for/of the video. Watch it, and you will understand. Although the video is in Mandarin, there are English sub-titles, so you shouldn’t have a problem understanding it.
