The "Go West" programme is a voluntary service programme which sends college graduates(毕业生)to work in less developed areas in China for 1 to 3 years. This national programme covers education, medical care, farming technology and so on. Many areas have benefited from(从中获益)the programme since it started in 2003, and Sheyit is among them.

Sheyit Primary School is a faraway village school in Xinjiang. Thanks to the "Go West" programme, many young graduates have arrived here to help. Although they come from different places across China, they all share the same wish: to bring hope and knowledge to the children and lead them to a brighter future in this way.
Those volunteer teachers at Sheyit Primary School devote(奉献)themselves fully to teaching the children and taking good care of them. They set clear rules in class and expect students to finish homework on time. They find that many parents are busy herding(放牧)animals and have little time to help their children with homework. The teachers work extra(额外的)hours so that they can help the students with their study. "This is where I find the true meaning of my life," a volunteer teacher here said. "When I see my students grow through my lessons, their progress(进步)becomes my honour."
The students also greatly treasure their teachers' teaching and care. They describe their teachers as being like the sun. They love going to school so much that some even come on weekends to study! Now all of them dream big and study hard towards their dreams.
“When active students meet hard-working and caring teachers, improvement is only a matter of time. Our school is no longer the worst in the city,”said Jin Wenbin,the leader of Sheyit Primary School. Since 2023,the school has produced many graduates who have done very well in local exams and got into top middle schools in Xinjiang.
