Important examples are the generation poems of the descendants of the Four Sages (Confucius, Mencius, Yan Hui, Zengzi): the Kong, Meng, Yan, and Zeng families (the Four Families, 四氏).

These generation poems were extended with the permission of the Chongzhen Emperor of the Ming dynasty, the Tongzhi Emperor of the Qing dynasty, and the Ministry of Interior of the Beiyang government.
