The word "主打" is formed by combining the character "主" (zhǔ), meaning "main" or "primary", with "打" (dǎ), meaning "to strike" or "to hit", where "打" is used figuratively to convey "to focus on" or "to target". Together, they create a compound where "主" specifies the central aspect and "打" indicates the action of emphasizing, resulting in a term that means "to mainly promote" or "to feature as the primary offering".
