The compound word 出海 (chū hǎi) is formed through a logical verb-object grammatical structure, combining the character 出 (chū), meaning "to go out" or "to exit", with 海 (hǎi), meaning "sea" or "ocean". Literally, it means "to exit (onto) the sea", which semantically extends to the act of setting sail, venturing out to sea, or metaphorically expanding a business or product into international markets. This formation is a classic example of how Chinese creates precise, action-oriented terms by pairing an action verb with its direct object or destination.
