I get a lot of those.
I barely understand Mandarin and not literate in Chinese.
So Chinese consulate calls, missing package calls in Chinese, and any text in Chinese are automatically spam for me.
I've trained my parents to never respond back to unknown calls and texts, and to ask myself or one of my brother's to double check the call for them.
@WilliamM2 Modern cell phones can be set it so that only people in your contacts will be able to reach you. Everything else goes to voicemail. And don't trust the caller ID data, it is very easily spoofed.
