Minor nit. Compound pinyin words shouldn’t use StudlyCaps so it should be “Lujiazui”

I think it should. Chinese language does not have the concept of word in writing, there is no space, and each character is a unit in writing. Pinyin was to mark pronunciations of each characters, it would be Lu Jia Zui, meaning 3 characters. Pinyin is not English. LuJiaZui would make it easier to pronounce if you don't know Pinyin. There is no standard way to write it though, maybe Lu-Jia-Zui, Lu'Jia'Zui, or Lu'jia'zui. The most confusing and would lead to wrong pronunciation version is Lujiazui.
