Cantonese is one of the popular languages in Macau. Under the special historical and cultural background, Macao has been in a multilingual environment for a long time, so it has formed a relatively distinctive Macao Cantonese system. This book will use pronunciation, words and language characteristics, supplemented by language phenomena that are seen daily but generally not noticed, to show readers the basic appearance of Macao Cantonese, and to experience the splendor and charm of Macao in the new era of triliteracy and multilingualism.
