Organized crime is rampant in South China.
Recently, a married couple in Hong Kong committed suicide and killed their two children because of gambling debt accrued in Macau and owed to triads (a collection of organized crime syndicates).
Most prostitutes in Hong are smuggled in from Shenzhen by triads. Counterfeiters are routinely caught.
The least they could do is smuggle in some quality weed or LSD, but they only know how to get meth, herion, meth and more meth. The Indians already have the smuggling shitty hash part covered.
