Even without really understanding Chinese characters, I often spot them (and use those offers sometimes).

Obviously I try to avoid US-American chains like McDonalds as much as possible, but local restaurants often run discounts too.

One thing in China to note is that discounts aren't given in "30% off", or "40% off", but rather the opposite. If you see a sign saying "9折" it doesn't mean 90% off, but rather 10% off.

This website does describe it pretty well:
