1. The Xia Dynasty was established, and China was transformed from a primitive society to a slave society.

2. The Shang Dynasty reform and the unification of the six countries by Qin Shi Huang transformed China from a slave society to a feudal society.

3. With the Opium War and the signing of the Treaty of Nanjing, China entered a semi-colonial and semi-feudal society from a feudal society, and China entered modern history.

There are no bounty points, and you don't know it.

Why are there only three of them? Where?

The earliest Great Wall of Qin is more than 2,000 years old, and the latest Great Wall of the Ming Dynasty has a history of four or five hundred years.

1. The Great Wall of the Qin Dynasty.

In the twenty-sixth year of Qin Shi Huang (221 BC), Qin annexed six countries, unified the world, and established the first unified multi-ethnic centralized state in Chinese history. In order to maintain and consolidate the security of the unprecedented unity of the great empire, Qin Shi Huang successively adopted a series of major strategic measures for national defense construction and border defense, one of which was the large-scale construction of the Great Wall.

In the thirty-second year of Qin Shi Huang (215 years ago), the general Meng Tian led an army of 300,000 to attack the Xiongnu in the north, took Henan Province, and then built the Great Wall of "starting from Lintao (now Shanni County, Gansu) in the west, ending in Liaodong (now Liaoning Province) in the east, winding more than 10,000 miles". Since Qin Shi Huang built the Great Wall, it has been called the Great Wall.

2. The Great Wall of the Han Dynasty.

At the beginning of the Han Dynasty, the Xiongnu took advantage of the war in China to cross the Great Wall built by the Qin general Meng Tian, and confronted the Han Empire with the Great Wall of Qin, Zhao and Yan as the boundary. Due to the disrepair of the Great Wall, the northern defenders were scarce, so the powerful Xiongnu continued to enter the Great Wall and plunder. However, it is such a dilapidated Great Wall, which also plays a military defensive role to a certain extent.

Cheng Buzhi is a famous general stationed on the Great Wall, and he governs the army strictly, as long as he guards the border Huns, he will not dare to attack. Its guards Qing, Huo Quzhi, Gongsun He, Gongsun Ao and others attacked the Xiongnu, all of which took Qin and Zhao Great Wall as the main bases for attacking and retreating.

3. The Great Wall of the Tang Dynasty.

For a long time, "there was no Great Wall in the Tang Dynasty" has been a foregone conclusion in academic circles, but the Tang Dynasty did build the Great Wall, but unlike the traditional "Great Wall of Hu Rejection", the Great Wall was built to unify the war. "New Tang Dynasty Book Geography" contains: Taigu County, Shanxi Province, "there is the Great Wall in Maling 80 miles southeast, 300 miles from Pingcheng to Lukou, and the year of Zhenguan is abolished."

The site of the Great Wall of Tang Dynasty is from Maling Pass along Maling to Guanshang (that is, the west of Guanshang Village in today's Shecheng Town), from Guanshang to Shiyuan Village, Yushe County, then to Huanghuagou, then to Shihui Village, Pipa Kiln Village, Jiaohongsi Village, and finally to Yicheng in Heshun County.

Fourth, the Great Wall of the Ming Dynasty.

The Great Wall of the Ming Dynasty is a military defense project built by the Ming Dynasty in the northern region, also known as the side wall, which is different from the Great Wall built by Qin Shi Huang.

In addition to the "outer" Great Wall, the Ming Dynasty built the "Inner Border" Great Wall and the "Inner Three Passes" Great Wall. The "inner" Great Wall is based on the construction of the Northern Qi Dynasty, starting from the west of the partial pass at the junction of Inner Mongolia and Shanxi, going east through Yanmen Pass and Pingxing Zhuguan into Hebei, and then to the northeast, passing through **, Fangshan, Changping counties, directly reaching Juyong Pass, and then from north to east, to the four customs of Huairou, connecting with the "outside" Great Wall, with Bauhinia Pass as the center, roughly into a north-south direction.

In many places, the "Inner Three Passes" Great Wall runs parallel to the "Inner Border" Great Wall, and in some places the two cities are only a few dozen miles apart. In addition, a large number of "heavy cities" were also built, and there were as many as 24 "heavy cities" in the area of Yanmen Pass.

The Seven Ancient Wonders of the World usually refer to: the pyramids of Egypt, the "hanging gardens" of Babylon, the temple of the goddess Aemis the moon god in Turkey, the bronze statue of the sun god of Rhodes in the Mediterranean, the lighthouse of Alexandria, the statue of Zeus in the Greek Olympics, and the mausoleum of King Mausolus of Turkey. However, due to **, man-made destruction and other reasons, these seven miracles, except for the pyramid still standing, the rest have been destroyed.

Therefore, on this basis, the theory of the Seven Wonders of the Middle Ages of the World was subsequently born.

The Seven Wonders of the World usually refer to: the Colosseum in Rome in Italy, the Catacombs of Alexandria on the edge of the Libyan desert, the Great Wall of China and the Stone Fence in Britain, the glazed pagoda of the Great Bao'en Temple in Nanjing, China, the Leaning Tower of Pisa in Italy, and the one in Turkey.

Before the Great Wall of the Ming Dynasty, there was already a city wall in the Spring and Autumn Period and the Warring States Period more than 2,000 years ago. The earliest history is more than 2,000 years old.

The year 2018 has a history of 2233 years.
