Your cell number is from an area likely to have a lot (i.e. 5%, maybe) of Chinese folks (especially visitors rather than permanent immigrants), it's a scam aimed at them and you're just among the collateral annoyed. It is easy/cheap/etc. enough for the robocallers to just hit all the numbers in your area in hopes of a few bites from those who speak Mandarin and fall for the equivalent of the IRS scam in Mandarin.
