school trip to cheongshim youth center
-------------------------------------
on 16th april, the playground of sinchoen middle school was very noisy.
all the students went to the school trip on the day.
it took only 30 minutes to cheongshim youth center by bus.
as soon as i arrived there, i was surprised at the nice building.
at the center, we leaned how to do cpr (cardiopulmonary resuscitation).
it would be very useful in the emergency situation.
i think cpr should be leaned to all people.
in the evening, we had wonderful recreation time.
we can not help enjoying the k-pop music and dance.
i spent very interesting and wonderful days at the center.
