What does it mean to say that "Pangu opened the sky, Huang San ruled the world, and the five emperors were determined"?

Pangu created the world, Huang San ruled the world, and the five emperors established the ethical system at that time.

Pangu: the great god in ancient mythology

Three Emperors and Five Emperors:

They are: Sui people (Huang San), Fuxi (Huang San), Shennong (Huang San), Huangdi (Five Emperors), Zhuan Xu (Five Emperors), Yao (Five Emperors) and Shun (Five Emperors).

I feel that Pangu is the frontier, Huang San is the rule of the world, and the five emperors are determined. The world is divided into four continents: ShenZhou in the east, NiuHezhou in the west, Wuzhou in the south and Luzhou in the north. This book list shows that Dongsheng wins China. There is a land overseas called Olego. This country is close to the sea, and there is a famous mountain in the sea called Guo Huashan. This mountain is the ancestor of ten continents and the origin of three islands. It has been in existence since the beginning and is tried by the HarmonyOS system. What a nice mountain!

In a few simple sentences, I explained the proud land of Huaguoshan and brought people into this magical world.
