How to understand Tao Yuanming's "If you get good things, you will feel the rest of your life" in "Return to Xi Ci"

I envy everything in the busy season and sigh that life is coming to an end. Tao Yuanming hated the filth of officialdom and abandoned his official position to retire, but his subconscious mind, deep in his heart, was always in turmoil. Admire that the creatures in nature thrive in chronological order, and lament that they can't do anything in their twilight years. I can't help sighing that there is nothing to worry about at the end of the year.

This famous sentence is good at conveying the psychology of the characters accurately and delicately. The poet touched the scene and touched people from the scene, describing the poet's political corruption in the country and corruption and bribery in the officialdom. However, due to the strict gate system, many people with lofty ideals are unable to display their ambitions and are in a state of grief and indignation.
