|Dr Hu Zhicheng is back in the US|
He was born in China and went to the United States where he became internationally known as an expert in the development of catalytic converters that are used to limit pollution in cars. With a doctorate in engineering, Hu holds almost 50 patents and has conducted research at the Massachusetts Institute of Technology and worked for multinational companies.
He believes it started when the businessman tried to sell him inferior components and Hu refused to purchase them, but the well-connected executive refused to take no for an answer.
Hu only wanted to help his mother country become better, and yet his fellow Chinese did not see him as one of them.
In the meantime, many credit Hu's daughter Victoria for campaigning for her father's release. She was able to visit her father in 2010 and put up a petition on change.org that collected over 60,000 signatures and set up a Facebook page called "Help Victoria's Father Dr Zhicheng Hu Come Home."
With his arrival, on Facebook she posted: "After 5 years, my dad is finally home! Watching him walk around trying to find the chopsticks is the best feeling ever."
Her mother tried diplomatic means to get her husband home, but somehow their prayers were miraculously heard on Monday.
While the Chinese government claims to warmly invite overseas Chinese to come back and share their knowledge, we're assuming Hu will never return to the motherland again. His ordeal is a warning to any Chinese outside the mainland that coming back can be like being in no man's land.
