北海之内有山，名曰幽都之山。黑水出焉，其上有玄鸟。“天命玄鸟，降而生商。”借助玄鸟形象，借此悼念在前线战斗而牺牲的英雄，“黎明”即将到来。

There is a mountain within Beihai, called the Mountain of Youdu. Where is the black water coming from? There are black birds on it. The destiny of the mysterious bird is to descend and give birth to commerce. With the image of the mysterious bird, we mourn the heroes who sacrificed their lives in the frontline battles, and the dawn is coming.
