I had no idea China had this problem, but it makes sense.

“… lockdowns and border closures forced criminal networks — many of which were involved in casinos — to look for alternative sources of revenue while also leaving migrant workers trapped in foreign countries and desperate for work.”

“[Scams] are a huge problem and a growing concern to the Chinese public, especially as many of those working in the call centres include Chinese nationals lured with the promise of legitimate work and then held against their will.”

“The issue was highlighted in a recent Chinese blockbuster film, No More Bets, in which a Chinese programmer and a model find themselves forced to work in an online gambling and fraud boiler room operation in an unnamed South-East Asian country.”
