The word "Joule of the Poor Family" comes from a fable in China's ancient classic Zhuangzi. The moral of this story is that even in poor families, outstanding talents may be born. This word also extends to talents regardless of wealth and rank, and everyone should get fair opportunities and treatment.

Joule was a gifted mathematician and astronomer in ancient China. He comes from a poor background and his family lacks financial resources, but he is smart and studious, likes thinking and works hard. In the case of extreme poverty, Joule still made outstanding achievements in mathematics, astronomy and other fields and became one of the outstanding scientists in history.

The idiom Joule, who comes from a poor family, tells us that a person's talent and ability have nothing to do with his family background. Even if you are born in poverty, you can become a talent through tempering and hard work. Therefore, society should provide everyone with fair opportunities for education and development, and avoid missing opportunities for training talents because of background. And everyone should cherish their own time and opportunities, study hard and make progress.
