I have fixed it,sorry. But pathetically,there are no legitimate support groups in China(my country) and only bastard training courses.(One of stutterers has ever recorded a dialogue asserting that in fact two of his pathologists are butching stutterers' money through the persistent courses that cannot be finished in one's lifetime to reveal the truths about our domestic stuttering training courses)So less and less domestic stutterers are having credits in so-called pathologists or training courses,and even stutter's reversibility..
