original text
These characters are gone, a few heroes who can make contributions, look at today's people.
To annotate ...
Let bygones be bygones. It's all over. All, all.
Countless romantic figures: heroes who can make contributions. Count, count, worthy of meaning.

The word "let bygones be bygones" swept through the history of China feudal society, turned to the present era of poet's life, and pointed out the theme of the whole word "count romantic figures, but still look at the present". "Today" is a new era, which needs new romantic figures to lead.
The "present" romantic figures will live up to the historical mission, surpass the heroes in history and have outstanding talents, which will surely create unprecedented achievements. This is the poet's firm self-confidence and lofty ambition.
