This was the catalyst that would later motivate him to start Teach For China.

He had arrived late at night at the secluded village perched on a mountaintop, after seven hours of traveling from the provincial capital in Kunming.

Pasinetti attended classes with the children in the school the next day and was bombarded with questions by curious students after class. The interaction left him the impression that the children were very smart.

He was shocked to learn later that few of the children he spoke with would get the chance to attend junior middle school, and almost none will make it to senior middle school. The headmaster said it was impossible for his school to keep teachers for long because the village was so remote, and conditions were very harsh.

"I remember his passion and eagerness to do everything possible to provide those children with a brighter future," Pasinetti says of the headmaster.

It was the same in other rural locations, and he heard the story repeated by local teachers and education bureau officials.

"They were really more eager for good teachers instead of more school buildings or multimedia classrooms," Pasinetti says.

Back in Beijing, he looked around for programs addressing this issue and found very few.

"I had the idea that perhaps I could do something to help alleviate the problem a little."

He called his college director and his parents in the United States and told them about his plan.

He never returned to Princeton University and is the only "high school graduate" in the program team.

Many people doubted his decision then, including Pei Yu, a classmate who has known Pasinetti since college.

According to Pei, Pasinetti seemed like a polite and well-groomed city boy who grew up in New York.

"It's hard for anyone to operate a nonprofit organization, let alone a foreigner. So I discouraged him then," Pei says. "He could have taken many other choices. I was surprised he decided to go into rural China."

Pei was later convinced by Pasinetti's passion and determination, and she later joined Teach For China. She has been there now for three years.

One of the changes she has observed in Pasinetti is physical. He now talks and acts like the locals when he visits rural schools, which was quite unimaginable when he first arrived in China.

Pasinetti says it's a conscious effort, and that he has tried to integrate into the community, including drinking for networking and working over meals.

While there are many challenges, he says the biggest one is to recruit really good teachers in a nonprofit organization and keep them in the rural communities. That takes the larger part of his energy and time.

"The nonprofit space in China is still very new. People tend to look for stable jobs and usually don't perceive a job with a nonprofit organization as a lifelong career," he explains.

"We all came into this work with a great sense of idealism. That's why we can stick to the program for so many years."

Yang Xiao, a former graduate student from Tsinghua University, applied for the program after he saw a poster on campus and started to teach at a rural middle school in Yunnan on a two-year contract.

The 26-year-old believes the teaching experience is valuable, and has stayed and became a recruitment officer.

"I believe it's a meaningful work, and I agree with the mechanism of Teach For China," Yang says.

Pasinetti says, "We have an ambitious plan for the future, and I hope to be part of that and help the organization achieve its goals."
