An increasing number of Chinese children are studying abroad. But sometimes the sense of displacement and emotional upheaval can take a heavy toll. Last month, a Chinese student at an independent boarding school in the UK was jailed after stabbing another student. He Minheng, who went to the Langley School in Norfolk, attacked another student with a knife. The victim sustained serious wounds to his shoulder and elbow. He was sentenced to four years in prison. The judge said it was a "serious, pre-meditated" attack on an "innocent, unarmed victim" whose injuries were "appalling", although not life-threatening. The defendant, who discovered his mother had been diagnosed with ovarian cancer when he returned to China on vacation, was left "isolated, alone and vulnerable", his defense team said. The case put a spotlight on the difficulties faced by Chinese pupils abroad. Reports China Daily
