How did Tao Yuanming see the darkness of officialdom?

Tao Yuanming is a talented poet and an idealist. Influenced by the bureaucratic family and Confucianism, he had the lofty ambition of "escaping all over the world" and "helping the general public greatly" when he was a teenager. However, at the end of the Eastern Jin Dynasty, there were frequent wars and the officialdom was dark, and his ideal was shattered. According to Xiao Tong's Biography of Tao Yuanming, Du You came to Pengze in the county and asked him to wear a belt to meet him. He "can't bow down for five buckets of rice, let alone strive for profits for the small and medium-sized people in the village", so he left his job today and was given a "return". "If he is rich, he will help the world, and if he is poor, he will be immune to it." Tao Yuanming finally chose the road of seclusion. That's all I know. I hope the landlord will adopt it as the best answer. I wish the landlord happy every day and successful studies! see you again
