We don't eat a lot of Chinese plum in our house. As far as I can remember, my mom uses it when she makes spiced duck. It's a very nice meal. The duck cooks for a long time in a slow cooker, usually overnight. She puts plum sauce, soy sauce and lots and lots of spices in it. This is also my dad's favorite. My mom makes it for dinner on his birthday every year.
I'm not a big fan of plums, but I like this dish too. The plum sauce adds a nice sweet and sour flavor to the duck.
