A Chinese reading topic: tea floats on the surface when it is just brewed, and then sinks to the bottom. What does it mean in life?

Dry tea leaves have less water and many gaps in the middle, indicating that there are many bubbles, so the density will be less than water, so they float on the water. Explain that at the beginning of life, you need to constantly learn and enrich yourself, otherwise it will be like this tea.

Bubbles disappear after soaking, and with water absorption, the density will be greater than that of water and sink. Explain that life has gone through a lot of tempering, understood a lot of truth, matured, became stable, and has connotation, just like this kind of tea soaked in water, constantly enriching itself and achieving the desired results.

Tea leaves float on the water because (the density is less than water).

Tea leaves sink in the end because (density is greater than water)
