In September, 16th, 2009, the School Students Union called
on all the teachers and students to do everything for the victims
of Typhoon Morakot in Taiwan.Some students write letters to
victims, encouraging them not to lose heart and tried their best to get
over the present difficulties.Every student gave away 20 yuan or
every teacher gave away 100 yuan. As well this, some students held
a charity bazaar (义卖) outside school to raise money for them. In last, we
collected about 120,000 yuan in all.Now all the money have been sent
to Taiwan through some organization. The disaster is not frightening.
Only if we unite and help each other can any difficulty will be got over.
