Sichuanese Pinyin

Sichuanese Pinyin (Si4cuan1hua4 Pin1yin1; ), is a romanization system specifically designed for the Chengdu dialect of Sichuanese. It is mostly used in selected Sichuanese dictionaries, such as the Sichuan Dialect Dictionary, Sichuan Dialect's Vocabulary Explanation, and the Chengdu Dialect Dictionary. Sichuanese Pinyin is based on Hanyu Pinyin, the only Chinese romanization system officially instructed within the People's Republic of China, for convenience amongst users. However, Hanyu Pinyin is unable to match the phonology of Sichuanese with complete precision, especially in the case for the Minjiang dialect, as there are many differences between Sichuanese and Standard Chinese in phonology.

Tones
The Sichuanese Pinyin system uses superscript numbers to mark the four tones of Chengdu dialect. The number is placed on the top right corner of every syllable, where "1" stands for the first tone, "2" stands for the second tone, and so forth.

Rules
The rules of Sichuanese Pinyin are based on those of Hanyu Pinyin, with some slight modifications:
 * When the final -ong has a zero-initial, it is written ong (as opposed to Hanyu Pinyin weng).
 * As in Hanyu Pinyin, ü is written u when paired with the series of alveolo-palatal initials (j-, q- and x-); however, the rule is not extended to the additional member ȵ- (e.g. 女 ȵü3).
