In Mainland China and Singapore, people use these simpler characters.
Chinese are used by the Han people in China and other races who have come to recognize themselves as Chinese.
Chinese is almost always written in Chinese characters. They are symbols that have meaning, called logograms. Chinese characters have existed for over 5000 years. Nowadays the Mandarin language uses Hanyu pinyin to represent the sounds in Roman letters.
