讲课或调查方言时,常须举出一些阴阳四声的例字。手头如无字表,急切中不易想起。古人有“天子圣哲”,今人也有“中华语调,非常好记”等等帮助记忆的口诀,但常不敷应用。戏作七言诗一首,八句代表八种声调,可能有助记忆。当然,这只是一个口诀,并非真的“诗”,更不是“七律”。 Lecture or survey dialect, often have to give some examples of yin and yang four sound. Without words on hand, eager not easy to think. The ancients have the “Son of Heaven and the Son of God,” nowadays also have “Chinese tone, very good mind” and so on to help remember the formulas, but often not enough application. The seven-character poem in the play, eight in eight tones, may help memorize. Of course, this is only a formula, not a true “poem”, but not “seven rules.”
