There was "Mandarin" in the Zhou Dynasty, which was called "Elegant Words". It is the earliest mandarin of the Han nationality. Confucius gave lectures to students in elegant words. The ancients of our country attached great importance to the unity of dialects in various places, so "Ya Yan" appeared.

The article Ci Hai Ya Yan said: "Ya Yan, which is called' * * * Homology' in ancient times, is symmetrical with' Dialect'." Kong Ying Da said in Wen: "Elegant words are reasonable." Yayan is the earliest ancient lingua franca in China, which is equivalent to the present Mandarin. After the Zhou Dynasty, with the migration of the capital, the basic dialects of Yayan were also revised, but most of them were still based on Beijing dialect.

In fact, it is "Mandarin"! ! If the language was unified after the Qin Dynasty, why didn't the history books mention that there was a senior profession of "translation" in the early autumn and the Warring States period? !
