Yu Huaji, a name that left an important imprint in Chinese history. He is famous for launching a rebellion and killing Emperor Yang of the Sui Dynasty. However, how did he achieve this?

First, we need to understand that Yu Huaji was an important general in the late Sui Dynasty, who enjoyed high prestige in the army. During the reign of Emperor Yang Guang of the Sui Dynasty, due to tyranny and luxury, the people suffered and social conflicts intensified. Yu Huaji saw this opportunity and decided to seize it, launching a rebellion to overthrow the Sui Dynasty.

Secondly, before launching the rebellion, Yu Huaji had made thorough preparations. He secretly contacted some generals and officials who had the same ideas and planned the rebellion together. They also secretly collected a large amount of food and weapons, making adequate material preparations for the rebellion.

Then, Yu Huaji chose to launch the rebellion when Emperor Yang was touring Jiangdu. They took advantage of Emperor Yang's absence and suddenly attacked, quickly occupying Jiangdu. Emperor Yang was forced to commit suicide, ending his life.

Finally, after killing Emperor Yang, Yu Huaji immediately declared himself the new emperor and established a new dynasty - the Tang Dynasty. His rebellion was successful, and he became an important figure in Chinese history.

Overall, Yu Huaji was able to launch a rebellion and kill Emperor Yang mainly because of his high prestige in the army, thorough preparations, choosing the right timing, as well as his decisiveness and determination. His actions changed the course of Chinese history and ensured that his name would be forever recorded in history.
