MTL words with double reverse mapping
Some MTL polysyllable words correspond to more than one valid POJ word. In most cases the original words are two syllables and become homophones after tone sandhi (the first syllable changes from high or curving-up tone to basic). After conversion from POJ or TL to MTL, they become homonyms as they share the same spelling.
