鸤鸠在桑,其子七兮。淑人君子,其仪一兮。其仪一兮,心如结兮。· The cuckoo in the mulberries | Breeds seven fledglings with ease. | An ideal ruler should take care | To deal with all men fair and square. | If he treats all men fair and square,|He would be good beyond compare.
(“The Cuckoo”,The Book of Poetry [Compiled in the Spring and Autumn Period])
