What do you hope to gain out of living in these places? There are plenty of foreigners who have been in Shenzhen for over a decade and are only marginally more interesting or successful now than when they arrived. The location rarely changes what's inside. If you find Shenzhen interesting, just come! It (and the rest of the HK+PRD megalopolis) is not even close to peaking in terms of creative or engineering output. Just bear in mind that there will always be a barrier. If you're thinking of turning into a local you need to be either (A) a skilled Chinese (B) an extremely well capitalized foreign company (C) an extremely skilled foreigner willing to spend years in the city and learn the language to fluency.
All that being said, you want to look for cities with strong population growth trends, very low wages, and huge levels of government investment. India is probably your best bet, though I know nothing about it other than what's in the news that they want to be the next China. That will be tough since India is missing some absolutely fundamental pre-requisites to the kind of growth China has had.
