What I am looking for is any sort of link between it and the officers stationed in Shanghai, China. For example was it something of a fraternal order, or was it just a "neat"saying? I think there was more to it because it would not have been easy to inlet it into the bayonet blades. I want to see if anything can be found, to include in my book. If one of you finds an answer I'll credit you in the book. So, all of you Googlers get your googlefu working and see what you can find.
