Living in this world is like climbing a mountain. You will always be blinded by various "clouds".
Wang Jiefu said it well: "Don't be afraid of clouds covering your eyes, just because you are at the top."
Some people choose to continue climbing, expecting that there will no longer be blinding clouds; others choose to clear the clouds and see the sun, to get rid of the haze; the remaining ones are blinded by the clouds, lose their direction, and eventually fall off the cliff, becoming a pile of bones at the foot of the mountain...
The floating clouds in the sky will eventually dissipate, but the "floating clouds" in people's hearts will never be easily driven away.
