Because he pays attention to maintaining his health and doesn't worry about worldly things. There are two secrets of Liang Wudi's longevity: First, Liang Wudi does not overwork for state affairs, but pays attention to health preservation. Many monarchs in history died young because they were too tired. Qin Shihuang, because he didn't trust others to participate in politics, asked local officials to send the letter to the central government and correct it himself. This also led to his long-term lack of sleep and poor health. He died at the age of 22.

Drawing on the experience of many people in the past dynasties, Liang Wudi decided to take good care of himself and enjoy his life. There is no need to live too tired because of political affairs. Liang Wudi was criticized by many ministers for his personality, but he was unmoved. He wanted to become a monk three times because he didn't want to bear the pressure. Although he was finally persuaded by the ministers of the DPRK, he still maintained his own style, and the ministers had no choice. In order to stop Liang Wudi from thinking about becoming a monk, ministers also dare not disturb him with politics, so that he can live a good life without being disturbed by the secular world, so he can live a long life.

Second, Liang Wudi lost his wife in his early years and stayed out of the harem for many years, so he didn't indulge himself and kept good living habits. Many monarchs are addicted to the beauty of the harem, so it is inevitable that their indulgence will lead to poor health, but Liang Wudi is different from them.

Liang Wudi had a beloved wife in his early years. She has been with him since he didn't proclaimed himself emperor, so he has deep feelings for her. However, this wife did not accompany Liang Wudi to the throne. From then on, Liang Wudi had little interest in women, so he seldom set foot in the harem and didn't indulge in this bad habit, so he lived for a long time.
