Yang Li said that the breaking time should not be too long, and 1~2 days is suitable for contemporary urbanites. During this period, people should drink water, eat vegetables or eat liquid food properly. You can eat a little vegetarian food during the valley, just eat 1~2 times a day, don't eat at night, and sleep on an empty stomach.
It should be noted that the valley is not suitable for everyone. If improper measures are taken, it will aggravate the degree of organ damage and threaten life; In addition, malnourished people lack various nutrients. If they don't eat for a long time, their organs will not work normally, resulting in impaired immune function.
"Bigu", also known as Quegu, Qugu, Juegu, Juegu, Jiegu and Jiegu, originated from Fang Xian's "not eating whole grains", that is, instead of eating whole grains, he filled his stomach with drugs, food and other things, or stopped eating for a certain period of time, which was a common way of health preservation in ancient times.
Pigu, often associated with persuasion, is called convincing to Pigu. Being convinced, as the name implies, is to take qi. After being influenced by Taoist thought, it is called taking essence or taking qi. This is the practice of replacing food with qi, and the method of breaking the valley with conviction is always emphasized by Taoism. Since the Han Dynasty, there has been a legend that Taoist priests were persuaded to break the valley, and there were also many imitators in previous dynasties.
