What did the Qin people say? Is it Shaanxi dialect?

People in the Qin Dynasty spoke politely, not in Shaanxi dialect.

Yayan, the earliest common language in China, is roughly equivalent to Mandarin. Later generations called the ancient sound elegant. Its phonetics is ancient phonetics. China attached great importance to the unity of dialects in ancient times, so there appeared dialects that appeal to both refined and popular tastes.

After the Zhou Dynasty, with the migration of the capital, the basic dialects of Yahua gradually spread. The Han Dynasty spared no effort to popularize Yayan. After Luoyang and Kaifeng, the capital of the Central Plains in the Tang and Song Dynasties, Ya Yan reached its peak and reached a sentence. Poetry in Tang and Song Dynasties emerged in large numbers, and neighboring countries scrambled to learn.

Yayan historical evolution:

Xia, Shang and Zhou Dynasties:

Before the Zhou Dynasty, there was no mention of the specific form of China people. According to legend, the standard language at that time was the predecessor of the standard language of the Zhou Dynasty. The recurring standard Chinese is generally regarded as the language in the Book of Songs, which is the elegant language in Luoyang. Yayan is mainly popular in the Central Plains of the Yellow River Basin with Luoyang as the center. Bibliography of Zhou Dynasty was written by Yin Shang in the period of Yin Shang.

Yin people learn from Xia people. The quaint dialect (the earliest common language in ancient China, equivalent to today's Mandarin) is the Xia dialect. Legend has it that the capital city of Xia Dynasty was built in Luoyang, Henan and its surrounding areas. Shangdu was also built in the Central Plains, with Luoyang as the center. Therefore, the standard pronunciation of refined Chinese in past dynasties should be based on Luoyang area. It is speculated that the standard pronunciation of ancient Mandarin is the ancient sound holo (modern Luoyang dialect).

Han dynasty and two dynasties:

The official language of Han Dynasty is "Luo language", which is an elegant language in Xia, Shang and Zhou Dynasties. The standard language of Han Dynasty is called "sound", "elegance" or "general language".

Wei, Jin, Southern and Northern Dynasties:

After the Eastern Han Dynasty, Cao Wei, the Western Jin Dynasty and the Northern Wei Dynasty successively established Luoyang as their capital, inherited the phonology of the Han Dynasty, and took the elegance of Luoyang as the national language. After the Eastern Jin Dynasty moved its capital to Jiankang, Luohan and Wu dialect merged to form Jinling Yayin, also known as Wuyin and Nanjing dialect, which was followed by the Southern Dynasties.

The Historical Influence of Elegant Words:

In the Tang and Song Dynasties, elegance reached its peak, reaching the height of a word. Poetry in Tang and Song Dynasties appeared in large numbers. Every neighboring country is competing to learn from Luoyang Yayan. The standard pronunciation of Luoyang dialect lasted for more than 4000 years, which had a far-reaching impact on neighboring countries such as South Korea, South Korea, Vietnam and Japan.
