"Don't forget the digger" originally meant that we drink water from the well every day and enjoy the fruits of our labor, but we can't forget the digger at the beginning. Metaphor to enjoy the fruits of others' labor, get benefits, do not forget its origin and the people who created the results at the beginning.

There is a village outside Ruijin called Shazhouba, where Chairman Mao lived when he led the revolution in Jiangxi.

There are no wells in the village, so the villagers have to go far away to fetch water. Chairman Mao led soldiers and villagers to dig a well.

After liberation, the villagers set up a stone tablet by the well, which read: "Don't forget to dig when drinking water, and always remember Chairman Mao."

The man who digs a well after dragging water is a narrative, which has been included in the Chinese textbook of primary schools in China [1]? . The work tells the story of Chairman Mao leading people to dig deep wells in Shazhouba when he led the Jiangxi revolution, expressing gratitude and admiration for his ancestors.

"Don't forget to dig a well and always miss Chairman Mao." This is a familiar, cordial and respectful word. For many years, when we bathed in the sunshine and sang happiness loudly, we would think of the outstanding leader Chairman Mao and his immortal feats of bravery, hardship and galloping on the battlefield.
