In which dialect should Li Bai's poems be read?

First of all, the language with the same pronunciation as Middle Chinese in Tang Dynasty should no longer exist.

The large-scale migration caused by politics or war has changed the pronunciation of various languages, but we can find that some places can better preserve the languages of the Tang Dynasty.

This ancient Chinese can include Minnan dialect (close to the early Middle Chinese, that is, the official language of the Tang Dynasty), Cantonese (close to the official language of the Song Dynasty) and Hakka dialect (during the Yuan and Ming Dynasties), because the ancestors of the users of these languages all migrated from the ancient Central Plains, some because of the war, and some because of the suppression of barbarians with the army.

The form of Min dialect is very old: your name is Ru, he is Yi, food is Yi, walking is Zou, noodle is Mian, black is Wu, pot is Ding, rope is rope, wing is Wing, stamp is Seal, house is Cuo, and cotton-padded jacket is Qiu. ......

So it is more appropriate to use Minnan dialect.
