My father, Dr. Zhicheng Hu, is an award-winning Chinese-American engineer whose work focuses on automobile emission control; he is listed as an inventor of 48 US, European and World patents. In November 2008, the Tianjin Police detained him while he was on a business trip to China after a competitor in Dagang-District, Tianjin, China accused him of “stealing technology.” In April 2010, Tianjin City Prosecutor’s office and Tianjin Court jointly withdrew the case against him and my father was freed without charge after 17 months of detention. Despite this, Tianjin Police continued the border control that prevents him from coming home to the United States without giving any reason. 

On November 10, 2011, two months after this petition began and 19 months after my father was freed without charge, the Tianjin police finally lifted the border control.  However, on same day, the Tianjin 2nd Intermediate Court placed my father under border control again, claiming that his competitor filed a civil suit against him on that day. My father paid the full amount requested to the court as collateral and asked the court to lift the border control. Then he was told that the competitor had withdrawn the civil suit and filed another one for the same matter, but this time asking for five times the amount of money. The "evidence" used by the competitor in this civil case is the same as that used in the prior criminal case. Their "key evidence" consisted of technical evaluations illegally concocted by an agency, which has been banned since 2008 due to perjury. Chinese law requires a civil case like this to be concluded within six months, which have long passed; however, the court continues to delay the conclusion and it has resulted in more suffering for our family.

My father has been separated from our family for more than four years due to this incident; in 2011, he underwent major surgery to fix an injury that he sustained during his detention. I was sixteen when we first learned of my father’s detainment. My world has changed a lot since then. My younger brother has been forced to grow up without a father for the past four years. My mother spent all of her energy trying to bring my father home and the stress has had a devastating effect on her health. We have tried many options, to no avail. Please, sign the petition and help us convince the Tianjin city government to lift the border control and let my father come home! Thank you!

请帮助我父亲胡志成博士回家 

我父亲胡志成博士是在汽车尾气净化领域颇有成就、对中国和世界环保事业做出了贡献的的海归工程师、48项欧美和世界专利的发明人，曾获得重要发明奖项。因被天津市大港区的竞争对手诬告偷窃技术、自2008年11月起遭到天津市公安局长达17个月的超期羁押；至2010年4月天津市法院和检察院撤诉、才重新获得了自由。但是，天津市公安局在法院撤诉后继续无理设置边控阻止他回美与家人团聚。

2011年11月10日，在此请愿活动开始后二个月、也是父亲被无罪释放19个月后，天津市公安局终于撤销了无理的边控。但同日，天津市二中院以竞争对手于当日提起了民事诉讼为由设置了新的边控。父亲支付了全额保证金并请求解除边控。 此时他又被告知竞争对手撤销了该状，却就此事又提起新民事诉讼并把索要金额提高了五倍。竞争对手在此案中使用的“证据”与以前刑事案的相同。他们的“关键证据”包括由一家机构违法炮制的技术鉴定，该机构因收贿做伪证于2008年被中国政府取缔。中国法律规定此类案件应在六个月内审结；此案现已一年，但法院却不断拖延使我们仍无法和父亲团聚。

迄今，父亲被与家人拆散已四年多，他的身体也在被羁押期间受到极大伤害、不得不接受手术治疗，至今仍在恢复中。父亲被抓时我十六岁，我的世界由此改变了很多。我弟弟也已四年无法得到父亲的关爱。为了救父亲我母亲日夜操劳，她的身心健康受到了很大影响。我们做了很多努力但都没有结果。万般无奈中我在此请求您在请愿书上签名，帮助说服天津市政府撤销对我父亲的边控，让我爸爸回家。谢谢您！
