Deletion of Chinatown patterns in Canada and the United States

Comment: The claim that there is "no sourcing whatever" was blatantly false.  It is easy to add more sources, as I have just demonstrated by adding a source where a citation was required.  There is abundant literature about this topic and so the claim that this is OR seems implausible and is not supported by any examples or evidence.  Deletion of promising material of this kind would be contrary to our |editing policy and the rest is a matter of |ordinary editing
