Question: In the 1990s, marked by the liberalization of language development and mother tongue movement in Taiwan, Taiwanese Hokkien had undergone a fast pace in its development. In 1993, Taiwan became the first region in the world to implement the teaching of Taiwanese Hokkien in Taiwanese schools. In 2001, the local Taiwanese language program was further extended to all schools in Taiwan, and Taiwanese Hokkien became one of the compulsory local Taiwanese languages to be learned in schools. The mother tongue movement in Taiwan even influenced Xiamen (Amoy) to the point that in 2010, Xiamen also began to implement the teaching of Hokkien dialect in its schools. In 2007, the Ministry of Education in Taiwan also completed the standardization of Chinese characters used for writing Hokkien and developed Tai-lo as the standard Hokkien pronunciation and romanization guide. A number of universities in Taiwan also offer Hokkien degree courses for training Hokkien-fluent talents to work for the Hokkien media industry and education. Taiwan also has its own Hokkien literary and cultural circles whereby Hokkien poets and writers compose poetry or literature in Hokkien on a regular basis.

Answer: When did Taiwanese Hokkien have a fast change in development?
