Meng jiu is a kind of bird that lives in the south. It always makes its delicate nest with beautiful feathers, and fastens the nest to the spikes of reeds（芦苇）.

Whenever there is a big wind, the nest always falls to the ground when the reeds break. All the eggs and young birds are killed. Disaster happens not because the nest Meng Jiu makes is not fast enough, but the reed that the nest is fastened to is too weak.

蒙鸠是南方的一种鸟，它总是柔软美丽的羽毛纺织成精巧细致的窝巢，并精心地系在芦苇的花穗上。

每当大风降临时，鸟窝常常因芦苇折断而掉下来，里面的蛋和幼鸟也被摔破摔死，无一幸免。蒙鸠的窝做得并不是不好，发生灾难的原因是因为它用来系窝的芦苇太不结实。
