About the official language of Han and Tang Dynasties

Let me talk about the official language of the Han and Tang dynasties. In the 3,000-year history of the Chinese nation, there has always been a common language, which is the Luoyang dialect of the Heluo area. In the Jin Dynasty, when Wuhu was in chaos, Luoyang Zhengyin followed the Jin Dynasty's clothes and traveled south to Jinling. In the north, there are too many ethnic minorities and the language is confusing. After Emperor Wen of the Sui Dynasty unified the world, he was also troubled by this problem. After fierce debate, he formulated an official language, namely: Jinling-Luoxiayin, which was used by the Tang Dynasty.

"Yan's Family Instructions·Yinci Chapter": "We used the imperial capital together, studied the local customs, assessed the ancient and modern, and made a compromise. After careful consideration, Jinling and Luoxia'er were the only ones."

So don’t come back to me to discuss ancient Chinese pronunciation and the like. If you really want to discuss it, please bring out historical data to prove that the official dialects of the Han and Tang Dynasties are different. Don't rely on your own imagination and experience.

At least the historical data I found show that from the Han Dynasty to the Tang Dynasty, the official language was always Luoxiayin, and the inheritance in the middle was not interrupted.

In the Tang Dynasty, the seven families and five surnames were regarded as orthodox among the Han people. Which one was not inherited in the south during the Wuhu period?

"Dujinling and Luoxia'er" has already proved that the Jinling and Luoxia sounds of Han and Tang Dynasties are the same thing.
