Emperor Qianlong was the fourth emperor in China after the Qing Dynasty entered the customs. He reigned for 60 years, and then for three years, at the age of 89. He is the oldest emperor in China. Then, people can't help asking, most of the ancient emperors in China were short-lived. Why did only Emperor Qianlong live so long? What ability did he have to prolong his life? This should be analyzed from two aspects. First, after Qianlong ascended the throne in 1735, foreign rebellion and invasion were put down one after another, thus safeguarding national unity and sovereignty; Internally, it strengthened imperial power and ideological rule, implemented an enlightened policy, advocated Chinese culture, and vigorously governed it, so it was once the heyday of singing and dancing, national prosperity and people's security. In times of peace and prosperity, Emperor Qianlong had no internal troubles and foreign invasion, so he could naturally travel leisurely in the south of the Yangtze River, travel around the mountains and paint poems. This pleasant and prosperous living environment is one of the reasons for the longevity of Emperor Qianlong. Second, Emperor Qianlong paid more attention to science and did not believe in alchemy. He has his own set of 16 words of health and longevity secrets. Namely: "Breathe in your heart, exercise your muscles and bones, often do ten things, don't do four things, and make up in time." "Breathe to the heart. It is to choose a place with fresh air outside every morning and use the breathing method of "mouth breathing and nose breathing" to spit out carbon dioxide and breathe in fresh air. " "Exercise your bones and muscles" means that Emperor Qianlong loved to play Tai Ji Chuan, walk, climb mountains and hunt. Moderate exercise can relax muscles and tendons, enhance physical fitness and enhance disease resistance. "Ten often. It is the ten parts of the body that should be exercised regularly, meaning: knocking teeth, swallowing body fluids, bouncing ears, rubbing nose, moving eyes, rubbing face, rubbing feet, moving abdomen, stretching limbs and lifting anus. Adhere to the "ten frequencies". , can mobilize the positive factors of the human body, dredge the meridians, and reconcile the exterior and interior, so as to achieve the effect of promoting blood circulation and regulating qi and resisting external evils. Gan Longsheng seldom got sick before he was born, which is inseparable from his insistence on using "Ten Frequencies". "Four noes" means eating without talking, lying without talking, drinking without getting drunk, and flirting. Gan Longshou's longevity is closely related to his "four noes". In addition, Qianlong also advocates taking some nourishing crystals with rich nutrition according to different seasons, so as to "replenish them in time". The above are two aspects of the longevity skills of Emperor Qianlong in Qing Dynasty, which can be used for reference.
