That's an easy one. 1. Receive the quest 2. Go to Hefei Tavern and buy one "Tai Bai Liquor". Tavern is next to the Hefei Clinic. 3. The next of step quest will be marked on the map. @ "Tomb to Lord Bao" the upper right corner of the map. 4. An Old Lady(Tuen Tanhua) will be there, give her the Liquor by opening quest dialogue. 5. Run back to the Cho Cheng to receive 5 Shabby Coupons as reward. Hope that's helps
