This proverb means "it is better to take the big than to take the small". That is to say, it is better to obtain it step by step and be solid and stable. The other side means working toward a goal that is not easy to achieve, but it is better to work towards some smaller goals that are more easy to achieve. Many small successes add up to big successes. The clever hunter, if his skill is not enough to shoot down the birds that fly high and far in the sky, will first try to shoot a few neighboring birds to make a sound.
From the bird's side, the big bird has a large goal and many enemies, and it is either coveted by hunters or rejected by its kind at all times. The humble bird, without these concerns and restraints, flies freely and freely, satisfying its tiny and sweet hopes one by one.
"Dapeng Anzhi Yan que joy" is also a kind of outlook on life, and it is the general people's outlook on life, which is more negative and more "defeatist". However, it seems that people have a tendency to choose this attitude towards life.
"Young people's lofty aspirations" is a needle in the face of this tendency.
