The nasolabial folds, commonly known as "smile lines" [1] or "laugh lines", [2] [self-published source] are facial features. They are the two skin folds that run from each side of the nose to the corners of the mouth. They are defined by facial structures that support the buccal fat pad.

Ware 1966: 138-139), Third, he describes how a beginning xingqi breath circulation practitioner should count their heartbeats to measure time during biqi ( 閉氣 , "breath holding").
