First of all, Zhou Yunli's action stems from her love for education and her enthusiasm for teaching students in mountainous areas. Zhou Yunli herself said that when she was born, she had no idea about these mountains and felt that she might live in them all her life. But after coming to Zhang Guimei's school, everything changed. She found that children in the mountains don't have to be in the mountains, but they can go out and get a better life and better study conditions. And Zhou Yunli herself worked very hard and was successfully admitted to a good university. However, this passion for letting children go out with their own mountains to change their lives, this idealistic feeling and this spirit of helping others can be said to have influenced her life, so she still insisted on her dream, which is her love for education.
Second, Zhou Yunli's actions are actually gratitude to Zhang Guimei and her alma mater. Without Zhang Guimei's school and this excellent and great principal, Zhou Yunli would not be here today, so Zhou Yunli is actually very grateful to Zhang Guimei for his teaching, and also to this school for his teaching. Therefore, Zhou Yunli returned to her alma mater with gratitude to help Zhang Guimei teach and educate people better.
I hope Zhou Yunli can go further and further on the road of teachers!
