"The overall function of the Three Treasures is thus, but if we are to talk about the respective functions of each, we have to mention one phrase."
"The upper burner is like mist, the middle burner is like foam, the lower burner is like a ditch?"
Lu Xuan looked at Ji Xiuwen in surprise, "You know about this?"
"I know a little." Ji Xiuwen nodded.
"Once when I was in school, I stumbled upon it in the library."
"Care to share?"
"Sure, but I don't know as much as you do."
"No worries, say as much as you remember."
Hearing this, Ji Xiuwen thought for a moment, then said, "The upper burner is like mist, meaning the upper burner disperses the qi and blood of the heart and lungs, like mist permeating, nourishing and warming the body's organs and tissues.
According to the divisions of the Three Treasures, the upper burner mainly refers to the chest, including the heart and lungs.
The heart is the master of blood, promoting blood circulation throughout the body.
