在美国联邦最高法院的大楼里,经常出入着一位着深色西装,个头不高、但却显得亲切干练的华人律师。他,就是胡知宇,一位来自大别山区的中国人,一个拥有美国一国三州执照的职业大律师。 In the building of the Supreme Court of the United States, a Chinese lawyer with dark suits, a low profile, but very friendly, often goes out and enters. He is Hu Zhiyu, a Chinese from the Dabie Mountains, a professional barrister who owns and licenses three states in the United States.
