What does KFC always shout? What do you mean by OR ETC ZIN HW POP CSTZ?

Hehe, hello. I'm its assistant. Let me tell you what it means:

Or the original chicken.

ETC refers to crispy chicken leg meat

HW is spicy chicken wings.

CST is boneless leg meat.

POP is the hottest popcorn.

Also, I would like to add that DT is egg tart and DR is spicy chicken leg meat.

I hope you can adopt it! thank you
