Question: When did the group, in which Canadian writer Wayson Choy is a member, develop a romanisation system for Catonese?
Context: Wayson Choy, CM (崔維新 Pinyin: Cuī Wéixīn ; Jyutping: Ceoi1 Wai4-san1) (born April 20, 1939) is a Canadian writer. Paper Shadows: A Chinatown Childhood is a non-fiction memoir, written by Canadian writer Wayson Choy, first published in October 1999 by Viking Press.  In the book, the author chronicles his experience growing up as an immigrant in Vancouver's Chinatown in the 1940s and 1950s. Jyutping (; ] ) is a romanisation system for Cantonese developed by the Linguistic Society of Hong Kong (LSHK), an academic group, in 1993.  Its formal name is The Linguistic Society of Hong Kong Cantonese Romanisation Scheme.  The LSHK promotes the use of this romanisation system. The romanisation of the Chinese language in Singapore is not dictated by a single policy, nor is its policy implementation consistent, as the local Chinese community is composed of a myriad of dialect groups.  Although Hanyu Pinyin is adopted as the preferred romanisation system for Mandarin, the general lack of a romanisation standard for other Chinese varieties results in some level of inconsistency.  This may be illustrated by the many variants for the same Chinese characters often found in surnames such as Low, Loh, Lo; Tay, Teh; Teo, Teoh; Yong, Yeong. Herbert Allen Giles (8 December 184513 February 1935) was a British diplomat and sinologist who was the professor of Chinese at Cambridge University for 35 years.  Giles was educated at Charterhouse School before becoming a British diplomat in China.  He modified a Mandarin Chinese romanisation system established by Thomas Wade, resulting in the widely known Wade–Giles Chinese romanisation system.  Among his many works were translations of the "Analects of Confucius", the "Lao Tzu (Tao Te Ching)", the "Chuang Tzu", and, in 1892, the widely published "A Chinese-English Dictionary". The Jade Peony is a novel by Wayson Choy.  It was first published in 1995 by Douglas and McIntyre. Peng'im (: Diê⁵ziu¹uê⁷ Pêng¹im¹ huang¹uan³(Teochew) Dio⁷ziu¹uê⁷ Pêng¹im¹ huang¹uan³(Swatow)) is a Teochew dialect romanisation system as a part of Guangdong Romanisation published by Guangdong Provincial Education Department in 1960.  Tone of this system is based on Swatow dialect.  The system uses Latin alphabet to transcript pronunciation and numbers to note tones.  Since Teochew dialect is a sub-dialect of Southern Min, Pe̍h-ōe-jī can also be used to transcript Teochew dialect.  The name "Peng'im" is a transcription of "拼音" using this system. Not Yet: A Memoir of Living and Almost Dying is a biography, written by Canadian writer Wayson Choy, first published in March 2009 by Doubleday Canada.  The author recounts his experiences following a combined asthma attack and cardiac arrest.  The book was favorably reviewed in "The Globe and Mail", and on straight.com. The New-French Latinisation of the Cantonese Language (Chinese: 新法蘭西粵語拼音方案, French: Système Nouvelle-France de la Latinisation de la Langue Cantonaise) is a romanisation system for Cantonese developed by the New-French Linguistic Society, a group of Cantonese students from Simon Fraser University, Canada.  The students' purposes were corresponding the broad IPA, transcribing different dialects/accents of modern Cantonese, correcting the "lazy pronunciations" and Cantonese teaching.  Thus the system tried to avoid alphabets with different pronunciations in different languages.  However, since this system is publicised later than other romanisation systems, and computerised info-processing was sacrificed for accuracy, the system is not yet widely used. All That Matters is a novel by Wayson Choy.  First published in 2004 by Doubleday Canada, it is the sequel to his debut novel, "The Jade Peony" (1995), and was nominated for the Giller Prize.
