《Hwa-dong-jeong-em-tong-seok-un-go》 is a rhyme book written by sung-won Park which has different phonological system from 《Sa-Seong-Tong-Hae》, 《Sam-un-seong-hwi》, 《Kyu-jang-jeon-un》. Its phonological system is quite similar with 《Deng-yun-tu-jing》, which shows Beijing sound in early 17th century. Four rhyme books of Chosun refered 《Hong-wu-zheng-yun》as a original script at preface, but their phonological system are all different from 《Hong-wu-zheng-yun》. Writers of rhyme book wrote different sound which actually pronounced in Beijing dialect. And this show unique identity of Chosun rhyme book.
