In Chinese usage, the cuckold (or wittol) is said to be “戴綠帽子” dài lǜmàozi, translated into English as ‘wearing the green hat’. The term is an allusion to the sumptuary laws used from the 13th to the 18th centuries that required males in households with prostitutes to wrap their heads in a green scarf (or later a hat).
Do Chinese snicker amongst themselves when they see a tourist wearing a green hat? I know I would
When I was in Japanese language school, this actually came up amongst the Chinese students in the group as it was an example in the textbook or something. Laughter was had and then they explained to the rest of us later.
