I agree it was a touching movie, even though with my limited brain power in the evening I was dozing a bit but I got the story and liked it!  It taught me one thing, that one should remind oneself to treasure the relationship and love between family members and friends.  The more we can and willing to let go of our own ego and think for others, the better chance we might have a good relationship with others; and therefore less regret.  There is a Chinese poem stateed as follows;

有花堪折直須折, 莫讓無花空折枝.

圖中是演日本爸爸的高倉健，及小演員楊楊的劇照。

千里走單騎的確是部好片子，片中描寫兩對父子關係，都令人動容。尤其是高倉健演的爸爸，爲了完成兒子的心願，從日本千里迢迢跑到人地生疏的中國雲南。在一個陌生的國度，他不止更深一層地體會了兒子内心的孤單世界，而且能夠及時發揮了幼吾幼以及人之幼的精神。我同意 Rosa 的推薦，是部值得看的好片子。
