The whole poem is divided into two layers. The first layer shows that you are ambitious. The second layer explains that you are incompetent and laments your own report. Maybe I want to show that I am ambitious, but my luck is unlucky, and I am always knocked down by reality. I may be incompetent and may not be appreciated by Bole, and then I can only forget about it! Sigh that things are impermanent, sigh that the hardships and bitterness of success have to depend on certain circumstances.
That's a bit of complaining! It's right to make heroes in times, but you have to work hard yourself!
