At the end of the Southern Qi Dynasty, powerful officials were in power and the clans were divided. Xiao Yan, who was born in a branch of the Xiao family in Lanling, had outstanding literary talent and outstanding strategy. He started his career with military exploits and became a powerful general in Yongzhou. He witnessed the corruption of the imperial court and the desperation of the people. Finally, with the help of his close friends Shen Yue, Fan Yun and other advisers, he resolutely raised an army to overthrow the decadent Southern Qi Dynasty and established the Daliang Empire. He became Emperor Wu of Liang Dynasty.
At the beginning of his ascension to the throne, Xiao Yan worked hard to govern the country, wearing clothes at night and eating at night. He was diligent and frugal, opened up the public, built water conservancy projects, and developed culture and education. The Liang Dynasty's national power flourished and its culture was dazzling, making it a rare heyday in the Southern Dynasty. He himself was erudite and talented, writing numerous books, especially on Buddhism. However, as he grew older, this talented and ambitious emperor gradually became addicted to Buddhism, devoted all his country's efforts to building temples, and sacrificed his life in Tongtai Temple several times, which was a waste of national power and the government gradually relaxed. He was too tolerant of the clan members and noble families, which led to corruption in the administration and numerous internal conflicts. In his later years, he became even more confused and confused. He believed in Hou Jing, the rebel general of the Northern Dynasty, and led the wolf into his house. In the end, the "Hou Jing Rebellion" broke out, and the prosperous Jiankang City was destroyed by the war. The eighty-six-year-old Emperor Wu of Liang was trapped in Taicheng and died sadly of hunger and regret, leaving behind a sad emperor legend that turned from prosperity to decline.
