Breaking the grain is similar to removing poison, avoiding the grain, denying the grain, breaking the grain, breaking the grain and stopping the grain.

Just don't eat whole grains, eat gas and absorb natural positive energy. It is a method of Taoist practice, which is now used to lose weight, preserve health and cure diseases. On the one hand, Taoism believes that people eat whole grains, and feces accumulate in the intestines to produce dirty gas; On the other hand, "Zhuangzi Xiaoyao Tour" describes the immortal behavior of "not eating grains, sucking wind and drinking dew" in order to achieve the goal of immortality. Nowadays, with the rising popularity of the valley, people have different opinions about the valley. Xinming Liu thinks in his book Begging for Valley Nature: "Begging for Valley is a method of keeping in good health with heart. Under the guidance of professional health care teachers, with the help of physical and mental exercises, we can start psychokinesis to turn off the acquired feeding system of human body and turn on the innate feeding system of human body, so as to adapt to physiological functions, expel and supplement them, coordinate and balance physiological functions, and advocate' more damage than deficiency'. Make the body reach a healthy state of balance between yin and yang, regulate body and mind at the same time, and improve body immunity. So as to make the body and mind harmonious and natural, social harmony, family harmony and life harmony.

origin

"Bi" originated in the pre-Qin period, about the same time as "Qi". The collection of etiquette works before Qin and Han Dynasties, The Core Monument of Yi Ming, said: "Carnivores are brave, food eaters are clever, gas eaters die as gods, and non-eaters die as gods." It is the earliest theoretical basis of the art of crossing the valley. There are similar records in Huainanzi Dizhi. There are also examples in On Earth. For example, in the Spring and Autumn Period, a lone leopard in Lu lived in a deep mountain and drank a stream. "He didn't wear silk and hemp, nor did he eat whole grains [1]. He is 70 years old and still has the color of a boy. " He is the earliest practitioner of breaking the valley recorded in Historical Records. In 1973, among the silk books unearthed from Mawangdui Han Tomb in Changsha, there is an article "Going to the Valley to Eat Qi", which is the earliest extant work before the Han Dynasty. There is a cloud: "Those who go to the valley eat pyrrosia. If you are heavy-headed, light-footed, and clumsy, you will be smashed (fried), depending on the benefit. " It means that when you first arrive in the valley, you often have top-heavy hunger, which must be overcome by "blowing". Here, the combination of Bi Gu and Hodge, like the deliberate combination of Hodge and Dao in Zhuangzi, seems to indicate the initial existence of these three technologies in the pre-Qin period, that is, their simultaneous appearance.

After the establishment of Taoism, many people inherited this technology and practiced the valley. According to the biography of Emperor Wu of the Han Dynasty, Wang Zhen, an alchemist in the Eastern Han Dynasty, was "broken for more than 200 years" (when it was the mistake of "Japan"-the note of the cited person), with beautiful meat and a horse and a horse, with several people. "The Biography of Fang Shu in the Later Han Dynasty" records: "(Hao) Meng can save energy for five or ten years, including jujube stones without eating." There is a story about how to avoid the valley in Cao Zhi's Taoist Debate, saying that he tried to "bow his head and sleep" and "walk and be at peace for a hundred days". Among the alchemists attracted by Cao Cao, Zuo Ci, Feng Junda and Lu all have divination. Ge Hong, a Taoist priest in the Eastern Jin Dynasty, opposed the idea that one-way crossing the valley could lead to immortality (he advocated that the person who chooses magic should be Xi, especially the elixir). He believes that one-way crossing the valley can lead to immortality, which is a "one-sided theory" of practitioners, but he does not doubt the fitness and longevity effect of crossing the valley. He said in "Miscellaneous Answers in Bao Puzi": "The remainder is more than three years and two years, all of which are light in body and good in color." Give a concrete example to prove that Shi Chun, a Taoist priest in the Three Kingdoms, often didn't eat for a month or a hundred days when he was treating people with qi. Hearing this, Emperor Wudi became suspicious and said, "This is called taking medicine and asking people to prepare. In spring, I only ask for three or two liters of water. After more than a year, the color of spring is fresher and the strength is the same. " "Feng Shengsheng, but swallowed their anger to break the valley for three years. Watching him climb the mountain all day and carrying heavy loads. " According to the Records of Wei's Old Records, Kou Qian, a Taoist priest of the Northern Wei Dynasty, gave him a recipe for inducing valley under the pretext of Laojun, and all the disciples got it. Donglai Taoist Wang lived in seclusion in Hanshan Mountain and was isolated from the world for more than 40 years. "Seven Signs of Yun Qi" has been published for five years. Sun Youyue "practiced calligraphy but took Guxian Pill for 67 years, and his face was light, moist and clean." According to the Biography of the Hermit in the Southern History, Deng Yu, a Taoist priest in Nanyue, "broke the valley for more than 30 years, only carrying water with mica sheets and reciting the Great Cave Sutra day and night." Tao Hongjing "Good Guidance Valley. He has lived in seclusion for forty years, and he is still very capable in his eighties. " "Biography of the Northern History of the Cottage" said that Taoist Chen and Xu Ze "refused to raise cotton wool, although it was cold in winter." According to the Book of the Old Tang Dynasty, Pan Shi, a Taoist priest in the Tang Dynasty, lived in Songshan for more than 20 years, "but drank water from pine leaves." His disciple Sima Chengzhen also taught him how to lure bait. According to the history of Song Dynasty, Chen Tuan, a Taoist priest in the early Song Dynasty, lived in Jiushiyan, Wudang Mountain. He "lived for more than 20 years, but he drank several cups every day". According to the biography of Ji Fang in Song Dynasty, Zhao Tiansheng "doesn't eat, but he has a fresh air. Every time I smell fire and eat gas, I vomit, only fruit and spring water are produced. " Chai Xuantong "over 100 years old, he is good at avoiding the valley and whistling, only drinking." History books and Taoist books are too numerous to mention. It can be seen that from the Han Dynasty to the Song Dynasty, the technique of crossing the valley has been very popular in Taoism.
