There is a sequence of knowledge, and there is specialization in the industry, that's all. What does this sentence mean? Where is it used?

I will hear the truth sooner or later. My knowledge and skills are different, that's all. It can be used in the misunderstanding of "being a teacher": the ability is not evaluated by age and seniority, but as long as the other party has something to learn, he can be a teacher to ask for advice.

From Shi Shuo

author

Han Yu (768 ~ 824), a writer, philosopher and thinker in the Tang Dynasty, was born in Heyang (now mengzhou city, Jiaozuo, Henan) and was of the Han nationality. Originally from Changli, Hebei Province, he was known as Han Changli in the world. In his later years, he served as assistant minister of the official department, also known as the Korean official department. Posthumous title "Wen", also known as Han Wengong. Ideologically, he is the founder of China's "orthodoxy" concept and a symbolic figure who respects Confucianism and opposes Buddhism.

Han Yu and Liu Zongyuan were both advocates of the ancient prose movement in the Tang Dynasty. They advocated learning the prose language of the pre-Qin and Han dynasties, breaking parallel prose and expanding the expressive function of classical Chinese. In Song Dynasty, Su Shi called him "the decline of eight generations of literature"; in Ming Dynasty, he was regarded as the head of eight great writers in Tang and Song Dynasties, and he was also called "Liu Han" with Liu Zongyuan, and was known as "a great writer" and "a literary master of one hundred generations". His works are included in Collected Works of Mr. Changli.

Excerpts from the original text

Saint impermanence teacher. Confucius studied under Tan Zi, Changhong, Shi Xiang and Lao Dan. Scorpions' disciples are not as clever as Confucius. Confucius said: If there are three people, there must be a teacher. So disciples don't have to be inferior to teachers, and teachers don't have to be superior to disciples. They have a good understanding of Taoism and specialize in their skills. That's all.

translate

A saint has no fixed teacher. Confucius studied under Zanzi, Changhong, Shi Xiang and Lao Dan. These people are not as talented as Confucius. Confucius said, "When several people walk together, one of them can be my teacher." Therefore, students are not necessarily inferior to teachers, and teachers are not necessarily more talented than students. They have heard about it early and heard about it late, and their knowledge and skills have their own specialties. That's all.
