Confucius, Laozi and Mencius all wrote those works when they were born.

Confucius, whose real name was Zhong Ni, lived from September 28th, 55 BC1year (August 27th) to April, 479 BC 1 1 year (February1day). Born in Changping Township, Qiaoyi (now Luyuan Village, southeast of Qufu City, Shandong Province). After his death, he was buried in Surabaya in the north of Qufu, which is now Kong Lin. Confucius was a politician, thinker and educator in the late Spring and Autumn Period. He is also the founder of Confucianism. One of the top ten thinkers in the world and one of the top ten thinkers in China is known as a "century-old teacher".

Confucius had a far-reaching influence on later generations. When he was alive, he was known as a "heavenly saint", "many heavenly eyes" and "immortal sage". He was one of the most learned scholars in the society at that time, and was called the most holy (saint among saints) by later generations, the teacher of all ages. He edited poetry books, defined rites and music, prefaced Zhouyi and wrote Chunqiu. Confucius' thoughts and theories have far-reaching influence on later generations. The Analects of Confucius is a classic work of Confucianism, compiled by Confucius' disciples and disciples. It is a book that records the words and deeds of Confucius and his disciples.

Laozi (600-470 years ago) (born in Shimao on February 15th in Wuding at the end of the Western Zhou Dynasty), surnamed Li Minger, was born in Qurenli, Li Xiang, an ancient county of Chu (now Lu Yi, Henan), Han nationality. He was a great philosopher and thinker in ancient China, the founder of Taoist school and a world cultural celebrity. Laozi, also known as Lao Dan, is said to be born with white eyebrows and white beard, so he is called Laozi; Laozi lived in the Spring and Autumn Period and worked as a librarian (equivalent to the director of the National Library) in Luoyi (now Luoyang, Henan). He is knowledgeable and versatile. When Confucius traveled around the world, he went to Luoyi to ask Laozi. In his later years, Lao Zi traveled west by Qingniu, wrote a 5,000-word Tao Te Ching (also known as Lao Zi) in Hanguguan (located in Lingbao, Henan), and finally disappeared here. Tao Te Ching contains rich dialectical thoughts. Laozi's philosophy and ancient Greek philosophy together constitute two peaks of human philosophy, and Laozi is honored as "the father of China's philosophy" because of his profound philosophical thoughts. Laozi's thought was passed down by Zhuangzi, and together with Confucianism and later Buddhism, it formed the core of China's traditional thought and culture. After the appearance of Taoism, Laozi was honored as "the old gentleman on the throne"; From the biography of the immortal, Lao Tzu has been honored as a fairy. Since the Han Dynasty, emperors of all dynasties have worshipped Laozi in Lu Yi, Henan. Tao Te Ching has more than 1000 foreign language versions, which is the most translated book in China.

Lao Zi wrote a book of 5,000 words, Lao Zi, also known as Tao Te Ching, before Hangu Pass. Tao Te Ching, The Book of Changes and The Analects of Confucius are considered to be the three most influential masterpieces in China. Tao Te Ching is divided into two volumes, about 5,000 words.

Tao Te Ching was later named. At first, Lao Zi's book was called Lao Zi, but there was no such name as Tao Te Ching. Its completion date was controversial in the past, but it is still uncertain. However, according to the date of "Laozi" on Guodian bamboo slips unearthed in 1993, it was written at least in the middle and early Warring States period.
