Where is Cao Cao's wasteland today?

Historians attach great importance to Cao Wei's reclamation, but some have not reached an agreement so far, so they have to say what they think is safe when describing it. The system of wasteland reclamation was perfected in Cao Wei, and its origin can be traced back to before the Han Dynasty. Our ancestors have attached importance to farming since ancient times, and anyone who holds the handle of the country knows that defeating or defending the enemy is inseparable from the supply of open food. Therefore, Chao Cuo's "On Your Millet" quoted Shennong's teaching and said: "Shicheng has ten hills, Tang Chi has a hundred steps, and its armor is a million, but when the millet dies, the Buddha can stay." Although "Shennong" is not a real person, it can be believed that the pretender came from at least the Warring States period. At that time, Shang Yang was "confined to Sanjin, but Qin was vast and sparsely populated, so the grass and status were inexhaustible. Therefore, he lured people from Sanjin to benefit his farmland and house. After three generations, he did not know military affairs, but did business at home, making Qin people make enemies outside."

The strategy of giving state-owned land to immigrants, cultivating it now, and then supplying military food with the grain produced by Shang Yang is similar to the purpose and situation of Cao Wei's raising people and fixing land. "Bamboo Chronicle" contains: "In the seventeenth year of Wei Xiangwang (the first 302 years), Han ordered the official doctor to move to Jiuyuan (now the west of Baotou City, Inner Mongolia Autonomous Region); In the thirty-third year of Qin Shihuang (2 14 BC), after the Huns were expelled, 44 counties were set up in Hetao area of Inner Mongolia Autonomous Region that year. The above two measures are obviously immigrants farming to support the army and strengthen the border defense. In "Biography of Zhufuyan", Volume I of Hanshu, Zhufuyan said to Liang Wudi: "The northland is rich, and the river is blocked from the outside. Meng Tian built a city to drive the Huns, turned to Cao Cao for introspection, and China used it extensively to destroy the roots of Hu. " Among them, the phrase "introspecting and guarding Cao Cao" also applies to Qin and Han Dynasties. If Qin Shihuang immigrated to counties and counties and did not intend to produce grain on the spot for the army to save food from the mainland, it would be underestimating the ancients. It can be considered that the opening up of wasteland began in the Warring States period and was completed in the Qin Dynasty.

Today's Yanzhou does not completely belong to Yanzhou, one of the ancient Kyushu. Geographically, the relationship between ancient Yanzhou and modern Yanzhou is tolerance and inclusion. No matter which version of history, ancient Yanzhou is very big. Now Yanzhou, as a district under the jurisdiction of Jining City, Shandong Province, covers an area of 65 1 square kilometer and is included in ancient Yanzhou.

The geographical location has become smaller, and the nature has naturally changed. However, it is still called Yanzhou, which is not a question of true or false Li Kui jy, but because of the changes in political history. You know, the concept of ancient Kyushu is also constantly changing. Or we can say that today's Yanzhou is a respect for history and has inadvertently become a historical business card.

In fact, the division of Yanzhou in past dynasties still belongs to a controversial geographical issue, and different books and dynasties have different interpretations of the specific location and origin.

According to legend, Yu Xia controlled water and divided China into Kyushu, namely Jizhou, Yanzhou, Qingzhou, Xuzhou, Yangzhou, Jingzhou, Yuzhou, Liangzhou and Yongzhou. During the Warring States period, Kyushu had a specific administrative region. During the Western Han Dynasty, Kyushu had a clear geographical position. Yanzhou governs Dong Jun, Chenliu, Yang Shan, Yin Ji, Taishan, Chengyang, Huaiyang and Dongping.

Eastern Han Dynasty, Jin Dynasty, Sui and Tang Dynasties, Song Dynasty, etc. The area under the jurisdiction of Yanzhou is constantly changing, but the name Yanzhou has not disappeared and has been preserved.

In a word, from the literal meaning of extension, ancient Yanzhou and modern Yanzhou have the same meaning. But from the perspective of area and specific geographical location, the two have undergone earth-shaking changes. Fortunately, today's Yanzhou has not let us down, with a high level of economic development and convenient transportation.
