Interesting to see where the zeros show up on the distance matrix (aside from the diagonal). The similarity between manti and shumai (siomay in the article) was quite a surprise:

But that's also where I noticed both guotie and wonton were on the list, although guotie is basically a generic term for "potsticker." It's usually a fried jiaozi although sometimes a fried wonton is also called a guotie.
