Is there any reason why Yang Guangjian is the capital of Luoyang? Is it necessarily related to canal digging?

1. Guanlong Group's checks and balances on imperial power and Emperor Yangdi's move to the capital

Guanlong Group originated from six towns in the Northern Wei Dynasty and was born out of eight pillar countries in the Western Wei Dynasty. These people are all soldiers, and they are a gate group formed by Xianbei nobles who married and sat with Han warlords after going south. They have their own faction's army, their own territory and sphere of influence, and hold the political and economic lifeline of the country. Yu Wentai, the founder of Guanlong Group, abolished the Western Wei Dynasty and established the Northern Zhou Dynasty. Yang Zhong, an important figure of Guanlong Group cultivated by Yu Wentai, was Emperor Wen of Sui's father, and there were not too many teenagers. Emperor Wen of Sui replaced the little emperor of the Northern Zhou Dynasty and established the Great Sui Dynasty. It happened that he was the grandfather of the little emperor of the Northern Zhou Dynasty. Later, when Li Yuan, who was also a member of Guanlong Group, built the Tang Dynasty, didn't he also rob his cousin Yang Guang of the throne? For more than 2 years, the throne has been in the hands of these relatives.

This Guanlong Group is different from other warlords. They all have strong strength and even independent economic sources. No matter who gets the throne, they dare not list the whole Guanlong Group as the opposite. On the other hand, other people in Guanlong Group will unite to check and balance the imperial power. In fact, to be more accurate, Guanlong Group seriously threatened the imperial power. Because in order to safeguard their own interests, they often have some independent political demands and even interfere with the emperor's personnel arrangements.

During the reign of Emperor Yangdi, five prime ministers were appointed, namely Su Wei, Yuwen Shu, Pei Ju, Pei Yun and Yu Shinan. The first two are figures of Guanlong Group, Pei Ju and Pei Peiyun are representatives of Shandong, and Yu Shinan is from Chen Dynasty. From this point of view, Emperor Yangdi tried every means to gradually get rid of the control of Guanlong Group. Emperor Wen of Sui, Emperor Wendi of Sui Dynasty, once built Daxing City, and readjusted the political forces around Chang 'an. However, because it is in the core area controlled by Guanlong Group, the effect is not great. But God gave Emperor Yangdi an excuse. Guanzhong area, although thousands of miles away, but the traffic is not convenient. In the Sui Dynasty, the population in Guanzhong area increased greatly, and the number of garrisons was huge, which led to a shortage of food. Especially in times of disaster, the emperor took his ministers to Luoyang for dinner. So Emperor Yangdi took this opportunity to build the East Capital and move it to Luoyang. In fact, the real purpose is to reorganize the cabinet and get rid of Guanlong Group.

Second, Luoyang in the world is more conducive to the control of the world.

Luoyang is located in the world, and it has been a must-have place since ancient times. The east will embrace the eastern plains, and the west will be defended by Hanguguan and Tongguan to Chang 'an. With Luoyang as the capital, it is more radioactive to the whole country and more conducive to controlling the world. You know, the Guanlong Group headed by the Emperor of Sui Dynasty belongs to the Northern Zhou Dynasty. Later, after the Northern Zhou Dynasty annexed the Northern Qi Dynasty, the political forces in Shandong began to enter the regime of the Great Sui Dynasty. Later, the Sui Dynasty destroyed Nanchen, and Jiangnan was also integrated into the unification of the Sui Dynasty. However, it lasted for 4 years of wars and disputes, and the artificial separation between economy, politics and culture made the unified Sui Dynasty difficult to manage. It will never be so easy to truly integrate population, politics, economy and culture. Therefore, Emperor Yangdi decided to dig the Grand Canal from Luoyang to Zhuojun in the north and Qiantang in the south. This is a costly project, but Yang Guang, the Emperor of the Sui Dynasty, did this great project that exhausted himself, but made great contributions to the future. After the construction of the East Capital, the North-South waterway will be dredged, and the materials from the land of fish and rice in the south of the Yangtze River can be continuously transported to Beijing, which can also transport a large number of materials to all parts of the country. Obviously, Emperor Yangdi Yang Guang had a dream of a big China in his heart.
