Yang Di visited Jiangdu three times.

Yang Di Yang Guang (AD 569 ~ 6 18) was a famous cruel, rainy and extravagant emperor in the history of China.

In the early years of Sui Dynasty, after the rectification and reform of Emperor Wendi of Sui Dynasty, social and economic prosperity appeared. After Yang Guang ascended the throne, in order to strengthen the control of the whole country, make the materials from the south of the Yangtze River more convenient to be transported to the north, and his personal pursuit of pleasure, he did two things from the beginning: first, he built a new capital in Luoyang, called the East Capital; The second is to dig a grand canal running through the north and south.

In the first year of Daye (AD 605), Yang Di ordered a large-scale construction to build Luoyang as its capital. This project is very huge, and more than 2 million migrant workers will be recruited every month to transport foreign materials and stones from the south of the Yangtze River. Many migrant workers are exhausted during transportation. Yang Di also ordered the construction of a big garden in the western suburbs of Luoyang, named "Xiyuan". Xiyuan is more than 200 miles around, and there is a sea in the garden. In order to decorate the West Garden like spring all the year round, colored silk was cut into lotus leaves in winter and put on the water for the emperor to watch.

At the same time, Yang Di ordered the recruitment of 1 tens of thousands of migrant workers from all over Henan and Hebei, and dug a canal from Xiyuan to Huaishui, named "Tongji Canal", which connected Luoshui, the Yellow River and the Huaihe River, and then connected the Han River and the Yangtze River. Then, the Grand Canal extends north and south. Excavate Yongji Canal to the north, and lead Qinshui into the Yellow River until Zhuo Jun. Dig south of the Yangtze River, from Jingkou (now Zhenjiang, Jiangsu) to Yuhang (now Hangzhou, Zhejiang) on the Qiantang River. It took less than five years before and after, and a grand canal of four or five thousand miles was built, connecting five major rivers: Haihe River, Yellow River, Huaihe River, Yangtze River and Qiantang River. The Grand Canal has played a positive role in China's economic and cultural development and exchanges and the reunification of the motherland. It is the crystallization of the sweat and wisdom of our working people.

Emperor Yang Di was particularly fond of going out for a cruise. In the autumn of 605, he took a huge team of more than 200,000 people to Jiangdu for a cruise. Yang Di and Xiao Hou took two four-storey dragon boats, with palaces and hundreds of palaces on board, all beautifully decorated. Then there is the big ship for ladies-in-waiting, civil and military officials and guards. There are always tens of thousands of ships lined up on the Grand Canal, end to end, for 200 miles. There are more than 80 thousand trackers pulling fibers on the shore. There are cavalry guards on both sides of the strait, and the flag covers the sky and the momentum is extraordinary. Because Yang-ti was drinking and having fun on the boat, people within 500 miles were forced to provide food. Precious and delicious food can't be eaten. Dig a hole and bury it. After living in Jiangdu for four months, Yang Di returned to Luoyang. In order to decorate an honor guard, hundreds of thousands of people were used, and the cost of money was amazing.

Later, Yang Di visited Jiangdu twice. Every time he cruises, people along the way will suffer a disaster. In order to get promoted and get rich, many officials competed with the emperor for gifts, desperately searched for the people's wealth and made a fortune.

When Yang Di went to Jiangdu for the third time, the rule of the Sui Dynasty was already crumbling, and the raging fires of peasant uprisings across the country had been ignited.
