Let's take a look at the first word "Jing". Essence in this sentence mainly refers to essence and essence in human body. According to the ancients, the essence hidden in the human kidney is the foundation of the kidney. A healthy person must be full of kidney qi and often have a successful career, because they don't just think about men and women all day, but do something meaningful. And some people, confused all day long, indulge in feasting, even if no amount of essence, can only be slowly hollowed out and become unhealthy.

In China's practice, there is a concept of health preservation called "Pigu", that is, through his own practice, he gradually got rid of his dependence on diet and reached a certain level, which is similar to the meaning of "hungry" that we want to talk about.

"Qi" here refers to the internal strength of the human body, which is necessary to maintain human life activities. It contains important functions such as consolidating essence and blood and transforming nutrition, which can help the body maintain circulation and protect various organs of the body.
