Back to childhood, aimlessly trailing the back roads of your hometown. The art itself requires a pure mastery of technique. Before departing, you must excel in departure; while away, excel in longing for home; lastly, excel in returning home.
思鄉的藝術也可以說是一種技術，如果想運用到爐火純青的地步，在未離鄉前要善於離鄉；在離鄉後，要善於思鄉；其後並且要注意善於返鄉。
