Pork Bbq Sauce Chinese BBQ Pork Sauce?

Chinese BBQ pork sauce? - pork bbq sauce

What is the sauce they use Chinese BBQ pork is thick and red light and sweet, and if I leave it to freeze overnight in the refrigerator, what kind of.
NOT sweet and sour sauce! for those who would say that.
I have the restaurant was there, but I do what it could be said, is everything he says, barbecue sauce was red, but nothing
I have this question here before, but it did not really answer the duck sauce, sweet and sour sauce, I tried that before and did not even thickness in the area and very sweet. just because the color red does not mean you have the same taste.

Can someone tell me in the right direction with a name or a recipe or something
