Sichuanese Pinyin (Si
4cuan
1hua
4 Pin
1yin
1; ), 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, there is also the problem that it 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.
