There is no difference, but the cycle is a little long.

Taoism is a health-preserving culture. Taoism pays attention to the cycle and thinks that seven days is a cycle. Actually, you don't need to pay attention to those. You can avoid the valley for eight or nine days, but the important thing is to let nature take its course and not be forced. Also, plan according to your actual situation.

"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.
