Those who eat gas will not die, and those who don't eat gas will not die. The ancients hoped to use the valley to recuperate the body and achieve the goal of longevity. The word Bigu is a professional Taoist term, which comes from Taoist health preservation &; Ldquo Don't eat whole grains & rdquo Taoism is obsessed with cultivating immortals and wants to achieve immortality through cultivation. Therefore, many methods have been developed to assist culture. The behavior of crossing the valley is to regulate the body and assist in practice. Later, it was introduced to the people and became a common way of keeping in good health for the ancients.

The earliest record about Pigu originated from Zhuangzi &; Middot, have a nice trip &; The mountain that ldquo used to photograph is inhabited by gods. If the skin is ice and snow, if you are a virgin, you don't eat grains, drink dew from the wind, ride a dragon in the clouds, and travel around the world. & amprdquo: In the remote Lonely Snake Mountain, there lived immortals whose skin was as white as snow, soft and beautiful as a virgin. They don't eat human fireworks, don't live on grains, suck air and drink dew, build dragons by clouds, and appear outside the four seas. This is the earliest record. Ancient sages believed that the true god would never die and would not eat grains. Although miscellaneous grains maintain people's daily needs, they still bring impurities and shorten people's life span. So later generations developed this method. ?

As a well-known health preserving method, there are actually two methods. There are two traditional methods: taking medicine and taking medicine. One of the main methods is to ban eating and emptying internal organs for a period of time. Adjust your breathing style. Turtle breathing and this way of breathing vary from person to person and may be deceptive. But most people don't last long. As for the effect, different people have different opinions, so I won't comment on it here.

Secondly, taking medicine to avoid the valley is to regulate the body function by taking a small amount of other Chinese herbal medicines (Rehmannia glutinosa, Polygonatum sibiricum, Lycium barbarum, asparagus, etc.). ) and other foods (black beans, red dates, chestnuts, etc. At the same time, it is forbidden to drink staple food. Taiping Sheng Huifang, which was officially revised in Song Dynasty, has a prescription to avoid valley. The secret recipe for the immortal to avoid the valley and stay in beauty consists of Poria cocos, chestnuts, sesame seeds and Chinese dates. It is boiled into a paste and taken twice a day, 50 grams each time. ?

Breaking through the valley is not useless. By breaking the grain, people's physical function is adjusted and intestinal waste is discharged. By controlling the energy intake and adjusting the body's function, for our species-rich modern society, we can recuperate after eating a lot of fish and meat on weekdays, and occasionally for a day or two. What I'm talking about here is taking medicine to ward off the valley. ?
