We discovered this bao lady near our hotel. Over the course of our stay, we returned several times for yummy bao. We coudn't figure out how she always kept a full tin of baos, but on our last visit, we discovered her dirty secret: she would move them from the case into the bin! (In case this doesn't seem weird to you, it's supposed to go the *other* way - the ones in the bin are supposed to be the freshest.) But still, they were yummy nonetheless!
