Did China say anything during the Three Kingdoms period?

The word China existed in the Zhou Dynasty, but it was not commonly used in the Han Dynasty, because in the Xia, Shang and Zhou Dynasties, a city was a vassal state, a country meant a city, and China meant a central city, that is, the capital. During the Spring and Autumn Period and the Warring States Period, the vassal states merged through various means, and finally formed seven great powers, which were finally unified by the Qin Dynasty. Because the enfeoffment system is no longer implemented in the world, the word "country" is rarely used, and the word "China" is rarely used to refer to the capital.
