"Puda" is the nickname of Puyang Vocational and Technical College, which is pure praise and has the feeling of hating iron and not turning into steel.

Teacher Chang is a beautiful legend in Puda. As the first famous teacher in the college, she has many fans and is famous for her dedication to teaching and not participating in the title of professor.

On the morning of Women's Day, the winter wind is still showing its last strength. In the classroom before the bell rang in the undergraduate teaching department, I met Mr. Chang, who had worked in the college for 8 months, bureaucratically. She is, as expected, dignified and steady, generous and refined. Thirty-six students majoring in chemical engineering and technology are sitting in the classroom with vigor and vitality. I listen to Mr. Chang's advanced math class as if I were listening to a concert, although it was like listening to a gobbledygook.

Here, I heard two most beautiful voices. One is teacher Chang's voice, such as drizzle, soft snow and songs and poems, which are refreshing; One is the student's voice. When Teacher Chang finished the given content and asked the students if they wanted to listen to it again, 36 voices said in unison, "Yes-". Full of passion and energy.

In this case, I can't restrain my desire to speak, although I am all thumbs under the charm of Teacher Chang. I described the scene of the upgraded library to my classmates: the warmest in winter and the coolest in summer. It is a vast treasure house of knowledge, which has become a place that teachers and students don't want to go, thus creating a poetic residence of "cherry blossoms are like snow and books are full of gardens". Teacher Chang was also deeply infected and led his disciples to cheer loudly: "Come on for the college." The students were in high spirits and cheered for the beautiful scenery to be realized.
