What is the next poem about knowing the depth of the river by yourself?

Proverbs: You know the depth when you go down the river, and you know the sweetness and sourness when you taste pears.

You don't know how deep the river is until you walk into it yourself. You don't know whether a pear is sour or sweet until you taste it yourself.

This sentence tells people that everything can only be truly understood by personal experience and cannot be taken for granted! Practice produces true knowledge, only by trying and actually doing it, not just thinking about not doing it. It's better to settle for the second best and be lenient. If you make waves, you really have to make waves. Otherwise, how can we make waves?
