Chinese Language: Traditional vs. simplified
In mainland China a simplified writing system is used, whereas in Hong Kong, Taiwan, and overseas regions the traditional script is being used. Starting from the second half of the nineteenth century, there was a growing consensus that the writing system constituted an obstacle to the achievement of a higher literacy rate. The simplified writing system differs in two ways from the traditional writing system: (1) a reduction of the number of strokes per character and (2) the reduction of the number of characters in common use (two different characters are now written with the same character). A large-scale reform was continued after the founding of the PRC. In 1955 1,053 variant characters were eliminated. In 1956, the Scheme of Simplified Chinese Characters, known later as the First Scheme, was promulgated by the PRC government. It was composed of 525 simplified characters and 54 simplified basic components of characters. The Second Scheme of Simplified Chinese Characters was promulgated in 1977 but was repealed in 1986 amid general disapproval.
Chinese Language: Mandarin vs. Cantonese
Mandarin is by far the largest of the seven or ten Chinese dialect groups, with 70 per cent of Chinese speakers and a huge area stretching from Yunnan in the southwest to Xinjiang in the northwest and Heilongjiang in the northeast. This is attributed to the greater ease of travel and communication in the North China Plain compared to the more mountainous south, combined with the relatively recent spread of Mandarin to frontier areas. Cantonese is spoken by the people of Hong Kong, Macau and Guangdong province, including Guangzhou (previously Canton in English). Most foreign Chinese communities, such as those in London and San Francisco, also speak Cantonese thanks to emigration from Guangdong.
