Dragon and Babu Jiaozi is a kind of strange things exploded by fighting monsters and sold to shops to get jiaozi. The quickest way to get jiaozi is to find a map with more monsters and less strange blood. For example, more and more strange things like Huanglong explode at a fairly fast speed, and the more jiaozi you get. Another way is to upgrade your fishing skills. You can fish at night and sell fish to shops, and you will also get a lot of jiaozi.
