One of the college students, Zhu Mengqiong, 20, who was born in a rural area and lost her mother at a young age, said she was quite touched by the positive attitudes the children held toward life.

"Before I came here, I often felt sorry for myself," she says. "Compared with my classmates who grew up in cities, I didn't have beautiful clothes or money. But the little kids here can make dinner, wash their laundry and do farm work on their own. Their bright eyes and stunning smiles made me realize my life is good enough and will become better in future."

Zhu recalls one unforgettable scene when she was teaching children to dance, when a girl with a deformed arm struggled to make a heart gesture using both hands (to show her love and gratitude) along with the music.

Besides sad stories like these, the team members also had to endure the extreme conditions in the mountains. Male volunteers had to bathe in the open and sleep on the school desks. They cooked for themselves, using whatever they could find from the limited supply of vegetables and meat available. Most of the time they ate potatoes.

"At first I couldn't bear the smell of the shabby restrooms, but soon I got used to it," says freshman Chen Yunxin, 19, adding that she had more than 50 mosquito bites on her legs during her stay there.

But despite the hardships, Chen said that after having worked as a volunteer teacher, it made her want to make a lifelong career of it.

"Although we just spent several days together, I feel our love for those kids was even stronger than their feelings for us. You cannot just leave without feeling concern for them. I want to see them attend high school and college in the future."

Every evening, the volunteers walked the children back home through the steep and narrow mountain roads. Sometimes they had to send them back two or three times because the children would secretly follow them back to the school again.

"When I walked a girl home today, she wouldn't let go of me. She sat down and cried, telling her grandmother that she wanted to go to Wuhan with me to attend school. The scene nearly made me cry," Chen Yunxin says.
