Heavenly Creations is an encyclopedia of ancient science and technology written by Song, a scientist of Ming Dynasty in China. Now it has been translated into many languages and spread all over the world.

When Song was young, he was bent on becoming famous through the imperial examination, but he had to take the examination in his twenties. Ten years later, he still failed to do it.

After careful consideration, he decided to give up his fame and study science and technology related to the national economy and people's livelihood. He summed up the production technology of farmers and handicrafts at that time, and wrote "Heavenly Creations" after hardships. The book records the production process of 18 series in detail, with hundreds of precious illustrations, leaving a valuable legacy for future generations.

Ban Chao in the Han Dynasty was ambitious and didn't pay attention to some small details. But he is filial and diligent in his heart, and he often does hard work in his life. He is not ashamed of hard work. He is eloquent and well read.

In 62 AD (the fifth year of Yongping), my brother Ban Gu was recruited as a school bookboy, and Ban Chao and his mother came to Luoyang with Ban Gu. Because of his poor family, Ban Chaochang was hired by the government to copy books to earn money to support his family.

He suffered from long-term copying. On one occasion, he stopped his work, threw down a pen, and sighed, "If a gentleman has no other ambitions and strategies, he should follow the example of Fu Jiezi and Zhang Qian and make great contributions in the frontier so as to win the title of Hou. How can he work between a pen and an inkstone for a long time? "

Later, Ban Chao went to the Western Regions as an emissary, managed the Western Regions in an orderly way, and was eventually named Prince after his return.

Don't give up, you won't get it. Give up getting it. Give up big, gain big. This has become the knowledge of more and more people.
