● Last month, some volunteers from Xi'an went to a middle school in the mountain area. They
gave away 40 beds, 2 computers and hundreds of books to the students. The school lies deep in
the mountains. Students have to live in the school. But the school was too poor to provide beds
for them, so they had to
sleep on the desks. Thanks to the volunteers, now the students can sleep on their own beds in
the school.
