You do know how they write in
China, don't you?
How can "
May" be spelled "
Mei" in
China if they use Hanzi, not Latin letters?
As long as you don't use Hanzi, i.e. proper Chinese characters, *all* spelling of She-Lan is *only* phonetical: writing in Latin characters, English-speaking people's style, of what those people heard when some Chinese people *spoke* the name She-Lan.
