Examples of true knowledge through practice:

1. Feng Zikai’s painting

The cartoonist Feng Zikai once drew a picture of "Selling Sheep": A farmer took two sheep to the mutton restaurant and sold them to the boss. A farmer looked at it but shook his head repeatedly and said with a smile: "I drew an extra rope."

Feng Zikai looked at his painting carefully: two ropes holding two sheep, where is the extra rope? Got the rope? At this time, the farmer told him: "To lead the sheep, you only need to lead the sheep. No matter how many there are, just a rope is enough!" Feng Zikai marveled.

2. Sima Qian's "Historical Records"

Sima Qian's "Historical Records" was respected by Mr. Lu Xun as "the swan song of the historian". He writes about historical figures and historical events so vividly and vividly, largely due to a nationwide tour he took when he was 19 years old.

When he traveled to Huaiyin, he traced the footsteps of Han Xin in his early years; when he visited Qilu, he paid homage to the Confucius Temple and observed Confucianism and customs; when he went to Pengcheng, he listened to the legends of Liu Bang, the founder of the Han Dynasty; when he arrived in Daliang, he paid homage to Lord Xinling for "stealing the talisman" The famous Yimen in the story of "Rescuing Zhao"... It can be said that Sima Qian was able to write an immortal history book because of his personal practice of traveling thousands of miles in his youth.

3. Li Shizhen's "Compendium of Materia Medica"

In order to complete the writing of "Compendium of Materia Medica", Li Shizhen traveled far and wide for inspections, went to the mountains to collect herbs and visited people with practical experience. He went through many difficulties and dangers, and left his footprints in the mountains and mountains rich in Chinese herbal medicine. During the day, we collect herbs in the mountains, and at night, we conduct in-depth and detailed research on each herb, from its origin, cutting and cultivation to seedlings, stems, leaves, roots, flowers and fruits, as well as its form, smell, and function.

Li Shizhen worked hard for more than 19 years and took down millions of words of notes. After dozens of repeated revisions, he finally completed his masterpiece "Compendium of Materia Medica" at the age of 60. The content is extremely rich and is a valuable heritage of Chinese pharmacology, making a significant contribution to the development of pharmacology in later generations.
