During the Warring States period, it began to have the name of Luoyang.

It is located in the north of the water, "the north of the water is yang", so the name is Yangyang.

During the Qin Dynasty, the Five Elements Doctrine prevailed, and Qin Shi Huang reasoned according to the "Five Virtues at the End", believing that Zhou had fire virtue, and Qin replaced Zhou, which should be water virtue, so he changed Luoyang to Luoyang.

Emperor Guangwu of the Eastern Han Dynasty Liu Xiuding was the capital of Luoyang, and was renamed Luoyang because of the fire virtue of the Han Dynasty.

It has now been partially corrected, and it seems that it has fallen into a strange circle that cannot be segmented, and it has not been modified. I hope that you will mention it from time to time, and Wushan will thank you.
