Fourth, everyone is unhappy or unfair sometimes, and doesn't show it to make others laugh or worry, but still want to live an optimistic life and smile. It's no big deal.

6. Life can't always be smooth sailing, nor can it always be stormy. No matter what happens, please remember to be free and easy, open-minded and optimistic, and your life will become better.
