Primitive Sino-Tibetan-Ancient Chinese-Middle Chinese (Hakka family, Minnan pronunciation)-Yuan, Ming and Qing Dynasties (Mandarin family, Yuandadu Mandarin, Nanjing Mandarin, Zhongzhou Yun Guan Mandarin,)
That is to say, ancient Chinese was spoken in the pre-Qin, Qin, Han, Wei and Jin dynasties, Minnan dialect was spoken in the Southern and Northern Dynasties, and then Mandarin was spoken.
Watching the video "Dubbing Gods in Ancient Chinese", Xia, Shang, Zhou, Qin and Han Dynasties said this kind of language that sounds like Russian Indo-European family.
Reading Chinese in the Middle Ages will lead to drinking; Reading Minnan in Sui, Tang, Southern and Northern Dynasties
Read aloud and think about a quiet night. Dadu dialect in Yuan Dynasty is similar to Mandarin. It sounds like Mandarin mixed with Hakka dialect, and Mandarin has been finalized.
Mandarin in the Yuan Dynasty depends on whether there are tones or not, and whether there are tones classified as Southern Mandarin or Southwest Mandarin.
The Ming Dynasty was bilingual, with the old school of Nanjing Mandarin (nicknamed Bai Ning for short) and Zhongzhou Mandarin (Peking Opera and Kunqu Opera were sung in Zhongzhou Mandarin or its derivative languages).
The Qing Dynasty spoke the inner city dialect of old Beijing. Today's Beijing dialect is not pure, mixed with Hebei Sanhe spinster dialect. During the Republic of China, I heard the old national accent on Li Ao: the small circle in the big circle, and the yellow circle in the small circle have been dismantled. Sanhe County, Hebei Province is the place where the old maid's words are mixed in. The eunuch dialect in Hejian County, Hebei Province, is too popular and impure in Beijing dialect now.
