These are the displaced Thu Thiem souls whose land was "collectivized" for private use--search youtube for how many Thu Thiem projects are under construction now. Remember that this area was a ghetto just a few years ago and most of the residents have to shwit in the river and drink from it, while right across you have the elites living in their high towers. These people now work the night for obvious reasons as they have more freedom in the informal econonomy. Like I said, if somehow in my next reincarnation, I become a Thu Thiem resident, I would definitely pick up the Chai Latte trade.
