Chinese-English refers to the use of both Chinese and English languages, often in contexts where speakers of one language communicate with speakers of the other. This can include code-switching, where individuals alternate between languages in conversation, or the use of English terms within Chinese sentences. In many urban areas, especially in China, Hong Kong, and Taiwan, Chinese-English is common in everyday life, business, and education. It reflects the growing influence of English as a global language and the increasing interaction between Chinese and English speakers in various fields, including technology and culture.
