What do you mean, "you don't have to dive the dragon, but Kang Long has regrets"?

These two sentences are from & gt& gt melon. Day 9: Hidden Dragon, no need. 92: Seeing dragons in the fields is good for seeing adults. 93: A gentleman works all day long, and if he is cautious at night, he will be sharp. 94: Or he jumped into the Yu Garden. He is blameless. 95: Flying dragons are good for seeing adults in the sky. On 9: Conquering the Dragon, he has regrets. "Hidden dragons don't need to be used": a symbol of water. "Flying" is the "flying dragon in the sky, benefiting adults" in the Ninth Five-Year Plan. Simply put, it means that when the preparatory work or the time is not ready or mature, don't rush to achieve success, but should "wait for the opportunity." If the time comes, it will be very important; If you have the opportunity to move, you can do a lot. "Kang Long You Regret": It symbolizes that the dragonfly is too high and has exceeded its limit. Simply put, it is to further improve on the basis of the Ninth Five-Year Plan. Metaphorically, because of excessive greed or arrogance, regardless of the objective laws of nature, there will still be regrets (or disasters) in the end. In other words, it warns people that enough is enough and happiness is not enough. I personally don't think so.
