The Cantonese Transliteration Scheme (simplified Chinese: 广州话拼音方案; traditional Chinese: 廣州話拼音方案; pinyin: Guǎngzhōuhuà Pīnyīn Fāng'àn), sometimes called Rao's romanization, is the romanisation for Cantonese published at part of the Guangdong Romanization by the Guangdong Education department in 1960, and further revised by Rao Bingcai in 1980.
Some of the non-professional Guangzhou-language tutorials and dictionaries currently published in mainland China also use this scheme.
However, speech patterns of most Cantonese speakers do utilize both types of consonants and the romanization scheme attempts to reflect this.
The only recognized medial glide in the Cantonese Guangdong romanization is u, which occurs in syllables with initials g or k and rimes that begin with a, e, i, or o.
Syllables with entering tones correspond to those ending in -b, -d, or -g. Sample transcription of one of the 300 Tang Poems by Meng Haoran:
