Original sentence: Qi is the (partial) pinyin romanisation (more properly transliterated as qì) of what was once transliterated, using the older Wade-Giles romanisation, as ch'i (and frequently mis-spelled as chi)
Edited sentence: Qi is a pinyin romanisation spelling, but in English and many other Western languages the word is often spelled as chi or ch'i, which, while not fitting the modern Chinese government scheme represented by pinyin, can often more intuitively represent Mandarin pronunciation of the word for English speakers.See Daoism versus Taoism
