Don't enter the house for three times (that is, Dayu controls water)

Dayu is an important figure in the history of China. The Xia Dynasty he founded was the first dynasty in the history of China, and the first in the Xia, Shang and Zhou Dynasties. Although Xia Dynasty was only a tribal alliance, it was very different from the centralized autocratic dynasty after Qin and Han Dynasties, and finally it had a national form, which made China's history enter the historical era of trust from the legendary era. Dayu's flood control is another great event in the history of China. Although many nationalities in the world have legends about floods, the floods in China must be particularly serious, which is also the reason for the idiom "Flood disaster", which holds that floods are more terrible than wild animals. Dayu controls water and makes everyone live and work in peace. He won the support of many tribes and became the leader of the tribal alliance after Shun.

In the 12th year of Jian 'an (207), when Zhuge Liang was 27 years old, Liu Bei visited the Caotang in Longzhong, Xiangyang, and met Zhuge Liang.

Study hard

Confucius liked reading Zhouyi in his later years.

There was no paper in the Spring and Autumn Period, and words were written on pieces of bamboo slips. A book uses a lot of bamboo slips, and these bamboo slips can only be read if they are woven together with cooked cowhide ropes. Usually roll it up and put it away, and open it when you look at it. The Book of Changes is difficult to understand and obscure. Confucius read it over and over again. In this way, the cowhide rope of bamboo slips has been worn off many times (Bian Wei Sanjue).

Even after reading these, Confucius was still not satisfied, saying, "If I can live a few more years, I can know more about the words and contents of Zhouyi."

"Bian Wei's Three Musts" describes diligent study.

This story comes from Historical Records Confucius Family.

Mencius' mother moved three times

Mencius, his name is Ke. During the Warring States Period, Lu was born in Shandong Province. My father died at the age of three and was raised by my mother.

Mencius was very playful and imitative when he was a child. His family used to live near the cemetery, and he often played the game of building graves or imitating others crying and worshipping. Mother felt bad, so she moved her family to the market. Mencius imitated the game of killing pigs by doing business with others. Meng Mu thought the environment was bad, so he moved his family to school. Mencius studied etiquette and knowledge with his students. Meng Mu thought this was what children should learn, so he was very happy and stopped moving. This is the story of the famous "Three Movements in Meng Mu" in history.

Meng Mu attached great importance to Mencius' education. Besides sending him to school, he is also urged to study. One day, Mencius played truant from his teacher Zisi and went home. Meng Mu is knitting. He was very angry when he saw Mencius playing truant. He picked up a pair of scissors and cut cloth on the loom. Mencius was so frightened that he knelt on the ground and asked why. Meng Mu scolded him and said, "You read like I knit. Weaving should be connected one inch by one thread, then one foot by one foot, and then one foot by one horse. It's not useful until it's finished. Knowledge must also be accumulated day and night. If you are lazy, don't study hard and give up halfway, it will become useless like this cut cloth. "

Mencius was deeply ashamed of his mother's teaching. From then on, he devoted himself to study, studied hard, practiced the teachings of saints, and finally became a generation of great scholars, known as "Asian saints" by later generations.
