Four ancient civilizations: ancient Babylon, ancient Egypt, ancient India and China. However, except for Chinese civilization, the other three ancient civilizations have disappeared in the long river of history.

The kingdom of ancient Babylon has long since disappeared in the desert. Now, the country based on the cradle of ancient Babylonian civilization is called Iraq, which has nothing to do with it. The once extremely prosperous hanging gardens are now only empty ruins.

In ancient Egypt, except for a few enigmatic pyramids, there were no signs of brilliant civilization.

India today is not ancient India. The representative of ancient India, "Halaba culture", has been extinct after foreign invasion and destruction. In summer, Greeks, Cypriots, rest people and British invaded India successively. It was not until 1947 that India officially became independent and established a republic. The civilization of ancient India has hardly survived to this day. I can't even read the text of archaeological discoveries. This shows that today's Hindi and ancient Hindi can no longer be compared, and India's indigenous civilization has completely disappeared.

For thousands of years, China, like ancient India, ancient Babylon and ancient Egypt, has been constantly destroyed by foreign civilizations. During the Five Chaos Period, the Han people in the hinterland of the Central Plains were almost slaughtered by the invading Hu people, and the Han people in the north moved south one after another.

At the end of the Northern Song Dynasty, Jurchen, who rose in the northeast, perished in the Northern Song Dynasty, which also brought serious damage to the Chinese civilization in the Central Plains. These two periods are the periods of population migration from north to south in the history of China.

The Yuan Dynasty and the Qing Dynasty were the two periods when China was ruled by foreigners, but one was overthrown and the other was assimilated by China culture. The period from 1840 to 1945 was the most dangerous moment in China, but China still stood firm and did not perish.

The whole Chinese civilization system, including historical records, ethnic changes, cultural systems, scientific and technological development, customs and habits, has been recorded bit by bit by Chinese ancestors and continues to this day. This is the proudest thing for every Chinese son and daughter.

So, what caused the Chinese civilization to continue to this day? The main reason is that China has a vast territory and a large population. However, no matter how many Han people are killed by alien invasions and bloody massacres, as long as the Han people continue to become extinct, the achievements of Chinese civilization can be guaranteed to be passed on. However, China is by no means the only place with a vast territory in the world. Why are there so many people only in China?

The geomantic omen culture handed down from generation to generation by the Han nationality has been passed down to this day, and its functions can be summarized in four aspects: determination, wealth, preciousness and longevity. The first is the people. To measure the quality of a family's geomantic omen, the first thing is to see whether the family's geomantic omen can flourish. With talent, talk about wealth, fame, health and so on. Fengshui culture plays an important role in any Hakka architecture that moves from the north to the south.
