As a metaphor for severe oppression, we often say that what a cow eats is grass and what it squeezes out is milk. This is what the modern litterateur Mr. Lu Xun said when he was chatting with his friends. Mr. Xu Guangping recorded this sentence in gratified commemoration. It was later collected as a famous saying by Lu Xun and was called the spirit of the cow.

What the cow eats is grass and what it squeezes out is milk.

Lu Xun said that I am like a cow, what I eat is grass and what I squeeze out is milk. Although these words obviously contain elements of artistic processing and modification by writers, after all, cows not only eat grass, but also feed. But whether you eat grass or feed, grass is low-quality food. Cows must have their own unique tricks for converting low-quality forage into high-quality milk.

The spirit of the cow is the spirit of selfless dedication, asking for little, giving a lot, and making contributions without expecting anything in return. This sentence vividly reflects Lu Xun’s spirit of surrendering his head and willing to be a cow for the people, and to be a cow for the people. Dedicate yourself to the end of your life and die.
