扩大

The Chinese word 扩大 (kuòdà) is composed of two characters: 扩 (kuò) and 大 (dà). The character 扩 originally meant "to dig" or "to expand", and it is often used in the context of expanding territory or increasing the scope of something. The character 大 means "big" or "great", and it is often used to describe something that is large in size or quantity. When these two characters are combined, they form the word 扩大, which means "to expand" or "to enlarge". This word can be used in a variety of contexts, such as expanding a business, increasing the size of a city, or broadening one's knowledge.
