How did the ancients describe breathing?

The ancients often used expressions such as "inhaling", "breathing" and "swallowing" to describe breathing. For example, in Su Shi's poems in Song Dynasty, there was a description of "absorbing the clear air between heaven and earth and fumigating the essence of the sun and the moon", indicating that the ancients would absorb the clear air between heaven and earth and spit out the turbid air in their bodies by inhaling and exhaling. In addition, there are also descriptions in ancient Chinese, such as "take a deep breath, and breathe with it", which shows that the ancients would adjust their physical and inner state by taking a deep breath. At the same time, the ancients also used "white waves and black waves, breathing around the throat" and other methods to enhance the depth and stability of breathing.
