What are men and women?

Dragonfly water is an implicit expression for both men and women. Between men and women, skimming usually refers to an implicit and euphemistic expression. When a man or woman likes another person but doesn't want to express it directly, she will express her mind through some subtle hints, eye contact or subtle hints in words. Dragonfly dipping in water is a very traditional calligraphy technique in China, which means gently pressing the tip of a pen, just like a dragonfly dipping in water, leaving a clear mark.
