《孟子·滕文公章句上·第四节》
尧在位的时候，天下还不太平，洪水成灾，四处泛滥；草木生长茂盛，禽兽大量繁殖，谷物没有收成，飞禽走兽危害人类，到处都是它们的踪迹。
当尧之时，天下犹未平，洪水横流，泛滥于天下。草木畅茂，禽兽繁殖，五谷不登，禽兽偪人。
When Yao was in power, the world was not yet peaceful. There were floods everywhere; grass and trees grew rampantly, and animals reproduced abundantly; crops failed. Birds and beasts harmed humans and could be found everywhere.
