《魏书·列传·卷十二》
所以《诗经》说 殷商的军队 ，又说 上天命令神燕降，降而生契始建商，住在殷土多宽广 。
故《诗》云 殷商之旅 ，又云 天命玄鸟，降而生商，宅殷土茫茫 。
Therefore, The Book of Songs states that "the army of Yin and Shang", and then states that "God ordered the divine swallow to descend, descending and giving birth to Qi to establish Shang, living in the vast land of Yin".
