Where is the birthplace of Hakka dialect?

As far as China is concerned, the ancient Han people all spoke Hakka dialect (Middle Ages), and they didn't believe watching the video of reading wine in Middle Ages. I was too lazy to take a screenshot, so I took a screenshot myself.

The video confirms that the Hakka-Jiangxi language family is the same language family when reading Medieval and Min languages.

Ancient Chinese was spoken all over the country. Later, Fujian people evolved from early medieval Chinese to seven major Min languages, not to mention early medieval Chinese.

Later, early medieval Chinese evolved into late medieval Chinese. Later, all China except Fujian spoke Chinese in the late Middle Ages. Later, Chinese in the late Middle Ages evolved from Wenzhou dialect, Wu dialect and Putonghua.

Fujian and Nanling became independent one after another, leaving only the middle ancient Chinese varieties (Hakka dialect and Gan dialect) spoken by Nanling, which became Wuzhou Guangfu dialect.

The middle ancient Chinese variety in Nanling was called Cantonese, and later it was misunderstood as Hakka when it moved to the sea.
