The next sentence of "One day the dragon will wear a phoenix" is "I don't believe that adults wear holes in their pants", which means that you won't wear rotten pants all your life, but one day you will be loyal to your wife, wear a dragon robe and a phoenix coat and get ahead.

First, the source? Cantonese proverb

Second, the original text

Bullying a white beard is not as good as bullying a poor young man. In the end, one-stop wearing a phoenix, I don't believe that pants wear a hole all their lives.

Third, explain

Bullying the elderly is not as good as bullying the poor young people, suggesting that young people have unlimited potential. If young people work hard, they will succeed in their careers sooner or later. They don't believe in pants with holes all their lives ("dragon wears phoenix" means success in their careers, "unbelief" means disbelief in Cantonese, and "hole" means something has holes in Cantonese).

Fourth, tell the truth.

Young people have unlimited development potential, so don't look down on them because of temporary frustration, because they don't know when they will have a successful career and won't become Amon in the military. However, just sitting still, there is definitely no chance of "phoenix nirvana". If you want to develop yourself, you must rely on the word "learning".
