Why did Yang Guang, a northwestern man, fall in love with the "Three Places in Yangzhou" in the south?

Emperor Yang Di loved the South because it was rich and prosperous. Whether for entertainment or national development, traveling all over the north and south is one of Yang Di's political goals.

Since the Jin Dynasty, the land of the Central Plains has been in constant war, and the northern region has been invaded by the Hu people, which has seriously damaged the economy. Due to the influx of immigrants from the north, the Jiangnan area has been greatly developed, and the Central Plains culture has been preserved to the greatest extent in the south. So from the economic and cultural point of view, the south was ahead of the north at that time, and Yangzhou was one of them. After the Sui Dynasty unified the whole country, it made Chang 'an its capital. Although its national strength is strong, it is unbalanced after all. There are a large number of dragon-watching nobles in the north, which seriously checks and balances the imperial power. Therefore, balancing the North-South relationship is the primary task of the Sui Dynasty.

Although Yang Di is called a fatuous man, his political vision and military vision are absolutely not bad. Therefore, Yang Di visited Yangzhou three times and built the Grand Canal, which allowed the materials from the south to flow into the north continuously, increased economic and cultural exchanges, and also played a role in restraining the expansion of the northern nobility. At the same time, Yang Di actively consumed the power of the northern aristocrats and launched a war against Koguryo, the main purpose of which was to balance.

However, Emperor Yang Di did have personality defects. The three visits to Yangzhou did achieve the original political goal, but every action was huge, consuming a lot of manpower and material resources, and the local officials exploited the people, which made people's resentment boil on his way. In fact, many of these events have the shadow of northern aristocrats. They were not willing to be weakened, but weakened the imperial power through the emperor's inspection. For Yang Di, the south and the north are watermelons, but he is too eager to manage them. As a result, the fish and bear's paw didn't catch him, which plunged the southern region into chaos, and the war in the north began to collapse again, and the country was ruined.
