we have experienced the life in army for seven days,which is tough but interesting.As far as i know ,in some countries graduaters from colleges must be compulsory soilders.However,the situation in P.R.china is quite different,for collegians don't have to go to military camp.In order to let them experience the toilsomeness of military ,collegions must process military training at the beginning of freshman year .After seven days toilsome training ,i've learned a lot of things i've never experienced.
