In BC 155, Liu De, the third son of Liu Qi, Emperor Wu of the Han Dynasty, was made king of Hejian. Liu De likes Confucianism very much. His clothes, manners and behaviors are imitated by Confucian scholars, and many Confucian scholars in Shandong are attached to him.

Confucianism has not yet become orthodox. After the war at the end of Qin dynasty, there were few ancient books and scholars left, and Confucianism was difficult to recover. At this time, Liu De, the king of Hejian, rose at the right time and said, "The ashes are exhausted, scattered and compiled, only preserved." Liu De has been king for 26 years, but he has never been involved in the political whirlpool of the king's struggle for power and profit. On the contrary, he devoted his whole life to collecting and sorting out China cultural ancient books.

In order to collect books, Liu De traveled all over Luoyang, Shandong, Hebei and other places. He is not afraid of hard work and practice. Anyone who hears of a good book among the people will personally buy it with a large sum of money and order someone to make another one for the people. He wants what he doesn't want to sell and never takes coercive measures.

This was difficult for most rulers at that time, so Liu Dexian became famous. Many intellectuals traveled thousands of miles to bring their ancestors' old books to Liu De. For these people, Liu Dejun gave them reuse and bonuses. His works include Poems, Zuo Zhuan, Zhou Guan and Book of Rites, and there are dozens of them.

Liu De also personally participated in the collation of ancient books. He took famous Confucian Achyranthes bidentata and Guan Changqing as doctors and Wang Ding as his teacher. He also recruited world-famous bachelors to study and sort out the books he obtained. Liu De's attitude in collating ancient books is very strict. He must organize a group of Confucian scholars to discuss, analyze, correct and proofread the ancient books with incomplete, unfamiliar characters and different versions, and then organize them into books.

After hard collating, Liu De sorted out a large number of primitive ancient books, which was really a timely help to the Han Dynasty, which lacked books. Liu De brought many ancient books, such as poems and books, to North Korea. Liu Che, Emperor Wu of the Han Dynasty, was very happy to see Liu De bring so many books, and held a grand ceremony to receive them every time.

Although Liu De devoted himself to the collation of ancient books, he fell ill because of the suspicion of Emperor Wu of the Han Dynasty and died in 130 BC. However, Liu De's works are still sought after by intellectuals, and Ban Gu made a biography for him in Hanshu, in which Liu De's "seeking truth from facts" was first evaluated.

2. Washington cuts down cherry trees.

When he was young, Washington's father gave him an axe. This new axe is shiny, and George likes to chop things around with it. He ran into the garden and saw a tree, which seemed to say to him, "Come on, cut me down!" " " .

George often sees his father's workers cutting down big trees in the forest. He thinks it must be a very interesting game to watch the tree fall to the ground with a bang. So George cut it with his little axe. Because the tree was small, it didn't take him long to cut it down.

Soon, his father went home. "Who cut down my lovely little cherry tree?" He shouted, "This is the only tree of this kind in this area. I spent a lot of money on it." He was very angry when he entered the room. "If I find out who cut down that cherry tree, I will-yes, I will-"

"Dad!" Little George shouted, "I'll tell you what happened." I cut down the tree with an axe. " His father's anger subsided. "George," he said, holding the little guy in his arms, "George, I'm glad you told me what happened. I'd rather lose a dozen cherry trees than you lie. "

Su Dongpo apologized to Wang Anshi.

Su Dongpo, a great writer in Song Dynasty, was a bachelor of imperial academy, and people called him Su Bachelor. Su Dongpo is brilliant, his articles are well written and his poems are well written. But no matter how knowledgeable a person is, it is impossible to know what's going on in the world, so sometimes he has to make some mistakes.

One day, Su Dongpo went to visit Wang Anshi, the prime minister of the dynasty. The servant of the Prime Minister led him into Wang Anshi's study, saying that the Prime Minister was on a business trip and would be back soon. He asked Sue to have tea later. After waiting for a while, the host didn't come back. Su Dongpo strolled to the table and saw a poem chanting chrysanthemums on the table. The poem was not finished, only two sentences were written: last night, the west wind crossed the garden, blowing yellow flowers and gold everywhere.

Su Dongpo couldn't help secretly laughing when he saw it: the west wind is obviously the autumn wind, and the yellow flowers are chrysanthemums, but chrysanthemums never dare to face the wind in Ao Shuang, and they are the most resistant to cold and freezing. Isn't it a big mistake to say that the west wind "blows yellow flowers all over the ground" Thinking of this, Su Dongpo's poems are full of enthusiasm. Unable to hold back, he dipped his pen in ink and wrote two sentences in the letter: autumn flowers are not better than spring flowers, and he said that he should sing with the poet carefully.

Su Dongpo put down his brush and stayed for a while. Seeing that his master had not come back, he got up and left. Besides, when Wang Anshi came home, he met Su Dongpo's words in his study. He just shook his head and didn't care about Su Dongpo.

Later, Su Dongpo went to Huangzhou to be the ambassador of Ying Yong.

Su Dongpo lived in Huangzhou for nearly a year. On the Double Ninth Festival, there are strong winds for several days. One day, after the wind stopped, Su Dongpo invited some friends to enjoy chrysanthemums in the suburbs. I saw that the chrysanthemum garden was full of colorful flowers, golden and bleak in the west wind.

At this time, Su Dongpo suddenly remembered the continuation of Wang Anshi's poems, and he was dumbfounded and speechless for a long time. He suddenly regretted that he had made a joke in the past and quickly wrote to Wang Anshi to apologize.

4. Copernicus Heliocentrism

/kloc-in the 6th century, Copernicus, a Polish scientist, put forward Heliocentrism at the age of 40, which denied the authority of the church and changed human's view of nature and itself.

At that time, the Roman Catholic Church thought that his Heliocentrism violated the Bible. Copernicus still firmly believed in Heliocentrism and thought that Heliocentrism was not contradictory to him. After years of observation and calculation, he completed his masterpiece "The Theory of the Operation of Celestial Bodies".

5. China's thought of seeking truth from facts.

Deng Xiaoping, the chief architect of China's reform and opening up, warned us in the early stage of reform and opening up that in the process of reform and opening up, we should not only emancipate our minds, but also seek truth from facts, proceed from the reality of China and take the socialist road with China characteristics.

Adhering to the "Socialism with Chinese characteristics" road has rich political connotations and is a powerful embodiment of seeking truth from facts. Under the guidance of this ideological principle, the implementation of China's reform and opening-up steps pays great attention to national conditions and public opinion. The successful experience of western countries, even if we want to learn and use it, only has practical significance in combination with the national conditions.
