气息 (qì xī): 呼吸

After running five kilometers, he was so tired that he was gasping for breath; his breathing was very rapid, and he couldn't even speak.

In the deep forest at night, it was completely silent, with only the rustling sound of the breeze through the leaves, giving people a mysterious atmosphere.

The old Chinese doctor took his pulse and said that his qi was weak, and he needed to take good care of his health.

Walking into this café, the air was filled with the aroma of coffee beans and soft jazz, full of a relaxed atmosphere.

After a winter of treatment, his condition finally improved, and his breathing became steady and strong.
