What does lettuce tell us?

Is the question "What does Rapunzel tell us?" The story tells us that:

First, you can't steal from others, otherwise you will be punished. If the old couple can put in a good word for the witch in advance, instead of secretly picking lettuce, there will be no subsequent tragedy.

second, justice will surely overcome evil. The prince and Rapunzel represent the just side. They don't lose heart, don't lose heart, and trust their own judgment. Finally, they lived happily together.

Third, you can't do anything halfway, you can't be half-hearted about life, and the difficulties are only temporary.
