Shi Yang in Song Dynasty was admitted to Jinshi when he was young. In order to continue his studies, he gave up the opportunity to be an official and went to Henan to study as a teacher.

One day, Shi Yang and Youzuo came to visit Cheng Yi and saw the teacher sitting in the room outside the window. They couldn't bear to disturb the teacher or give up the opportunity to ask for advice, so they stood quietly outside the door waiting for him to wake up.

But it snowed heavily in the sky, and it rained harder and harder. Shi Yang and Youzuo are still standing in the snow. When Cheng Yi woke up, the snow outside was already a foot thick.

At this moment, Shi Yang and Youzuo came in through a foot of snow. Later, Shi Yang became a world-famous scholar, which was also regarded as an example of respecting teachers and attaching importance to Taoism. It became a much-told story in academic circles, and thus evolved into the idiom "Cheng Menxue Pear".

2, Yan Hui seized.

Yan Hui is a great disciple of Confucius. On one occasion, Yan Hui followed Confucius around the world and was trapped between Cai and Guo. He has no food and has not eaten rice for seven days.

Sleeping there during the day, Yan goes back to beg and cooks when she gets it back. It's almost cooked. Confucius saw Yan Hui grabbing the rice in the pot with his hand. After a while, when the meal was ready, Yan Hui invited Confucius to dinner, and Confucius pretended not to see Yan Hui's pilaf.

Confucius got up and said, "I just dreamed of my ancestors." I will eat clean food myself and then give it to them. "

Yan Hui replied, "That's not true. Just now, charcoal ash floated into the pot and stained the rice. If I can't throw it away, I will catch it and eat it. "

Confucius sighed: "you have to believe what you see, but what you see may not be credible;" You have to trust your heart, your heart can't be trusted. Remember, it's not easy to know someone. "

3. Emperor Han Ming

Huan Rong is the teacher of Emperor Han Ming, and Ming Di has always respected this teacher very much. Once Ming Di went to Taichang Mansion, where there was a teacher's desk and chair, so he asked the teacher to sit in the east, and called all civil and military officials to pay tribute to the teachers and students on the spot, and personally worshipped Huanrong as a teacher.

Ming Di can put down his noble status to respect the teacher, which shows his intentions and demeanor, and is worth learning.
