They are South Asians, but not necessarily Indians. One of them is named "Foisal" or Faisal I think. Faisal is a common Pakistani name.
I doubt that the average Indian is gonna find much job opportunities in China if ever at all. The Chinese job market is ruthless, and for foreigners to get hired, they need to have exceptional talent and discipline to even stand a chance. 99% of Indians, with their well known reputation by now will stand almost no chance of finding work in mainland China. HK is where historically, Indians have a decent chance of getting hired. Taiwan is now the new job frontier for Indian workers, so that's where the most Indians should be trying out.
