arm drag meaning in Chinese

拉臂

While the count was being turned over , one of his arms dragged helplessly behind , and he made a vain effort to pull it after him . whether the count noticed the face of horror with which pierre looked at that lifeless arm , or whether some other idea passed through his dying brain , he looked at the refractory arm , at the expression of horror on pierres face , again at his arm , and a smile came on his face , strangely out of keeping with its features ; a weak , suffering smile , which seemed mocking at his own helplessness
