Hainanese Transliteration Scheme

The Hainanese Transliteration Scheme was developed in 1969 by the Hainanese linguists. Its romanisation system does not use diacritics; instead uses tone numbers.

Alphabet
The alphabet consists of 26 letters. Note: C, F, J, K, Q, R, T, W and X are only used to write loanwords.

Tones
Tones are indicated by superscript numbers 1 to 8.
