What is the origin of the phrase "enriching the people and killing the people"?

This poem comes from Zhang's "Goat Tongguan Nostalgia" in Yuan Dynasty.

Original poem:

The peaks are like gathering, the waves are like anger, and the mountains and rivers are like Tongguan Road. Looking at the western capital, I hesitated.

Sad Qin and Han dynasties, ten thousand palaces have been made of earth. Xing, the people suffer; Death makes people suffer.

Translation:

Huashan peaks gather from all directions, and the Yellow River is raging. The Tongguan Ancient Road connects Huashan Mountain in the interior and the Yellow River outside. Looking at the ancient capital Chang 'an, I wander and my thoughts fluctuate.

Sadly, all the palaces in Qin Gong's Han Que have already turned to dust. Once prosperous, the people suffered; Once destroyed, people are still suffering.

Poetry appreciation

The author relates the dangerous terrain of Tongguan to its historical position, and then thinks of the dynasties of Chang 'an, which is not far from Tongguan, and Chang 'an, whose capital is Chang 'an. Chang 'an is not only the capital of Qin and Han Dynasties, but also the capital of Wei, Jin, Sui and Tang Dynasties. As the ancient capital of the Six Dynasties, it was so prosperous. Today, the luxury of the past has long gone up in smoke, leaving only a dilapidated scene. How can this not make the poet hesitate and sad?

But the poet's feelings are not only the sadness and hesitation about the rise and fall of dynasties, but also the concern for the people. Through sober reflection on history, the poet realized: "Prosperity is what people suffer; It is the value of the poet to point out that the painful situation of the broad masses of people will not change because of the change of dynasties.
