Why is Chu a battle of traditional powers?

The Seven Heroes of the Warring States refer to the seven countries of Qin, Han, Zhao, Wei, Chu, Yan and Qi, among which Qin, Chu and Qi are traditional powers. Qin was the founding vassal state of the Eastern Zhou Dynasty, which was founded by force. It was one of the five tyrants in the Spring and Autumn Period. Qin is very powerful. Chu is a small country established in the early years of the Western Zhou Dynasty. When the People's Republic of China was founded, its territory was 50 miles, and it was later destroyed by more than 70 countries. During the Warring States Period, the Chu State was 3,000 miles long, which greatly shocked the south of China. Qi was the founding emperor of the Western Zhou Dynasty. At the beginning of the founding of the people's Republic of China, the country was ruled by the strong and the weak. He once destroyed countless countries and was the first of the five tyrants in the Spring and Autumn Period. His brilliant martial arts had a great influence on the Central Plains.

In a sense, Chu is a traditional big country handed down from generation to generation. After all, the history of Chu State is hundreds of years longer than that of Qin State, and Qi State in the Warring States Period was Tian Qi, not Jiang Qi. The State of Chu was founded in 1042 BC and perished in the first 223 years. At the beginning of the founding of the People's Republic of China, it was Chu, with a territory of five miles around Danyang. The emperors of Chu made great efforts to make the country a giant, and the whole south of China was Chu. At the beginning of the Spring and Autumn Period, Chu claimed to be a barbarian, which seriously threatened the summer in the Central Plains. Conquest with Chu personally, and as a result, a war of words ended, and neither Qi nor Chu dared to go to war. The capital of Chu has been attacked many times, but with its strong national strength and vast territory, Chu has regained the capital many times.

The road to the founding of Qin is very difficult, even more difficult than the road to entrepreneurship in Chu. The State of Qin (905-206 BC) experienced five stages: royal princes, kingdom princes, principality, kingdom and empire. In 905 BC, due to his meritorious service in raising horses, he was made a vassal of the Emperor by Zhou. In 770 BC, Qin Xianggong sent troops to escort Zhou Ping eastward, became a vassal, and acquired the land west of Qishan. From then on, Qin officially became a vassal state of the Zhou Dynasty. Around 623 BC, Qin Mugong dominated Xirong and destroyed the country 12 years, benefiting thousands of miles. He was awarded the title of Xibo by the Zhou royal family, and Qin was promoted to the principality of Qin. In 325 BC, Qin Huiwen became king, and the Principality of Qin was upgraded to the State of Qin. In 22 1 year BC, the Qin dynasty destroyed six countries, the king of Qin proclaimed himself emperor, and the state of Qin was upgraded to the Qin empire.

Qi (1044-22 1) is a powerful country in the traditional sense. Qi is not only stronger than Mazhuang, but also rich. Since King Taigong sealed the state-owned country, the State of Qi boiled salt to reclaim land, and when it spread to Qi Huangong, it was already a big country on the border of the sea. Qi Huangong also relied on marine resources and quickly became the first of the five tyrants in the Spring and Autumn Period. Qi was called the land of Neptune at that time. When Jiang Ji reached Jikanggong, the doctor Tian He exiled Jikanggong to an island by the sea, "to eat a city to worship him first". Tian He stood on his own two feet and benefited Taigong Tianqi. In 386 BC, Tian and Ping were established, and the State of Qi was changed to Tian. In 334 BC, Qi Weiwang and Wei Huiwang became kings in Xuzhou, and Qi was upgraded to Qi.
