If you wish to dispute my comment, please provide anecdata or a peer reviewed study or poll/survey that supports your view.
Also, you wrote <<All the way back from 70s to 90s after it was a fishing village>> This statement makes no sense. Deng Xiaopeng did not 'open' Shenzhen until 1979. It was still a small, regional city well into the 1980s. It wasn't a multi-million person metropolis until the mid-1990s.
