"Pigu" originated from "not eating grains" in Taoist health preservation, and it was a common way of health preservation in ancient times. It originated in the pre-Qin period and was popular in the Tang Dynasty. Also known as "Valley Valley", "Valley Valley Valley", "Valley Valley", "Valley Valley" and "Hugh Valley". The earliest record of Bigu originated from Zhuangzi Xiaoyao Tour: "The mountain shot by the ancients is inhabited by immortals. If the skin is ice and snow, it is like a virgin, not eating grains, sucking wind and drinking dew, traveling around the world by flying dragons ... "As a way to prolong life, it is also recorded in many ancient books.
Traditional ways of breaking grain are mainly divided into two kinds: taking medicine and taking medicine. Persuaded to break the grain mainly through hunger strike and breath adjustment (breathing), but its effectiveness lacks scientific basis at present; Taking medicine to avoid cereal is to adjust the body function by taking other complementary foods (nuts, Chinese herbal medicines, etc.). ) instead of eating the staple food (grain).
Under the guidance of science, it is indeed beneficial to the health of the body, but the efficacy cannot be exaggerated, and the scientific principle needs to be studied.
Bigu is also called Gucci, Gucci, Digging Valley, Curved Valley and Broken Valley. Taoism believes that when people eat whole grains, feces will accumulate in their intestines, which will produce foul smell and hinder the road to longevity. Therefore, Taoism imitates the immortal behavior described in "Zhuangzi Xiaoyao Tour", hoping to achieve the goal of becoming immortal.
The ancients also often used crossing the valley as a method of health care. There is a saying in the book of washing marrow that "eating less will make you happy, and eating more will make you live longer". It can be seen that the valley has the function of prolonging life; Biography of Historical Records and Liu Hou: "Zhang Liang is sexually transmitted, that is, he does not eat grain." It is said that guiding the valley is a method of treating diseases. Anyone who walks in the valley should insist on eating gas and omnivorous medicine bait except cereal and wheat meals.
Begging for grain originated in the pre-Qin period, and it was about the same time as qi-moving. "Yi Ming Xin Bei" is a etiquette monograph before Qin and Han Dynasties. It says: "The carnivore is brave, the food eater is clever, the gas eater is alive, and the non-eater is dead." It is the earliest theoretical basis of the art of crossing the valley. There is a similar record in Huainanzi Terrain Training. After the establishment of Taoism, many people inherited this technology and practiced the valley. From Han Dynasty to Song Dynasty, the art of divination valley was very popular in Taoism.
During the period of 1973, two qigong cultural relics that attracted worldwide attention were unearthed from the Han Tomb No.3 in Mawangdui, Changsha, Hunan Province: the guide map and the chapter "Eating Qi in the Valley". The former is a colorful silk painting with various guiding postures; The latter is a silk book that records the specific methods of eating qi to avoid valley, and it is the first monograph on valley-avoiding therapy in China. According to textual research, the silk script was written in the early Han Dynasty, about the period of Hui Di (206- 188 BC). Its content and details may be ancient anecdotes handed down from the pre-Qin period.
