Abstract
At May the 29th， a mountaineering team from Bush Walker Club of
Shenzhen City gathered at the foot of Wutong Mountain to carry out
their weekly activity. Unlike any other ordinary mountaineers， this
team had a noble goal---to clean the litters scattered in the bush of
the mountain. These amateurs were well equiped and trained， with good
discipline and skillful leader. They chose a secret wild unknown path
to reach mountian top（approximately 1000 meters above sea level）. The
most impressive character of this activity was the complex terrain
conditions and dramatically changing weather in the mountain. Although
the team gave up to conquer the peak because of the dangerous thunder
hovering ahead， this acitivity can still be described as exciting，
impressive and successful.
