The Chinese word 开发 (kāifā) is composed of two characters: 开 (kāi) and 发 (fā). The character 开 originally meant "to open" or "to begin", and it is often used in the sense of "to develop" or "to exploit". The character 发 originally meant "to send out" or "to emit", and it is often used in the sense of "to develop" or "to grow". When these two characters are combined, they form the word 开发, which means "to develop" or "to exploit". This word is often used in the context of economic development or the development of natural resources. For example, the phrase 开发新区 (kāifā xīnqū) means "to develop a new area", and the phrase 开发石油 (kāifā shíyóu) means "to exploit oil".
