This is a kind of complementarity. People cannot be perfect. The east is not bright and the west is bright. They are brave enough to face challenges, bitter before sweet, and work hard. Even if it doesn't look good, it can't be changed. After graduation, I have a successful career through my own efforts. With profound knowledge, my status will be improved and my heart will be enriched. In this way, the whole person will be full of confidence, more brilliant than those who only have beautiful faces and don't want to make progress.
