But the man became a pigeon son to not only fly, process finally flew back for fly of two dayses, fly to village of time he saw him a beloved woman, just ratio past distressed a lot of, he diligently want to fly to chemisette nearby, but more near more see not pure chemisette face, be he fly to chemisette front of, woman disappear, at he at present but is a tree, on the leaf that is from this tree branch fall in the every drop Ta water bead of the Ta, elephant that spring the continuing light drizzle of the sort, water bead dozen wet snow-white pigeon son, but the pigeon son still keep strongly and without intermission looking for his beloved woman, see that mythic fungus grass will floating about, pigeon son any further have no some energy, he fall on the tree branch of this tree and surround on all sides, suddenly he shout loudly 1, a thing with red Xing drop down from the tree, at it fall in of place, long a small tree, but the pigeon son so and forever stop at tree up, expect of look in the eyes' being clear be long separation waiting for, looking for of lover.

而男人变成了一只鸽子不止的飞，经过了二天的飞翔终于飞回来了，飞到村口的时候他看到了他心爱的女人，只是比以前憔悴了很多，他努力地想飞到女人的身边，可是越近越看不清女人的脸，当他飞到女人的跟前时，女人消失了，在他眼前却是一颗树，从这颗树枝的树叶上落下了滴滴嗒嗒的水珠，就象那春季般的绵绵细雨，水珠打湿了雪白的鸽子，而鸽子还是拼命地不停地寻找着他心爱的女人，眼看着那颗灵芝草就要凋零，鸽子再也没有一点儿力气，他落在这颗树的树枝上，环绕着四周，忽然他大叫一声，一颗腥红的东西从树上掉下来，在它落下的地方，长出了一颗小树，而鸽子就那么永远地停在了树上，期盼的眼神分明在等待着、寻找着久别的恋人。
