大约九百年前，中国是北宋的时候。有两个读书人，一个叫杨时，一个叫游酢。他们都很爱学习。
About nine hundred years ago, China was in the Northern Song dynasty. There were two scholars, one named Yang Shi and one named You Zuo. Both of them loved learning.
他们想找一个好老师。当时有一位很有名的老师，叫程颐。他知道很多道理，很多年轻人都来跟他学习。
They wanted to find a good teacher. At that time there was a famous teacher named Cheng Yi. He understood many deep ideas, and many young people came to study with him.
杨时那时候已经四十岁了，也读过很多书。可是他觉得，自己还要跟程颐学习。
Yang Shi was already forty years old at that time, and he had read many books. But he felt that he still had more to learn from Cheng Yi.
有一天，杨时和游酢一起去程颐家。那天下着大雪，天很冷。
One day, Yang Shi and You Zuo went together to Cheng Yi’s house. It was snowing heavily, and the day was very cold.
他们走进屋里，看见程颐坐在椅子上，闭着眼睛。他正在休息。
They went into the room and saw Cheng Yi sitting in his chair with his eyes closed. He was resting.
两个学生没有叫醒老师，也没有走开。他们站在旁边，安安静静地等。
The two students did not wake their teacher, and they did not leave. They stood beside him and waited quietly.
雪一直下。过了很久很久，程颐才慢慢睁开眼睛。
The snow kept falling. A long, long time passed before Cheng Yi finally opened his eyes.
他看见两个学生还站在那里，心里很感动。他再看看门外，地上的雪已经有一尺深了。
He saw that the two students were still standing there, and he was deeply moved. Then he looked outside the door: the snow on the ground was already a foot deep.
后来，杨时读了很多书，也教了很多学生，成了一位大学者。人们用“程门立雪”这个故事，教大家要尊敬老师，认真学习。
In later years, Yang Shi read many books and taught many students, and he became a great scholar. People use the story of “standing in the snow at the Cheng gate” to teach a simple lesson: respect your teachers and take your studies seriously.
