The Chinese word 往来 (wǎnglái) is a compound formed by combining two directional verbs with opposite meanings: 往 (wǎng), meaning "to go (towards)," and 来 (lái), meaning "to come." This pairing creates a binome, a common lexical structure in Chinese, which conceptually captures the idea of reciprocal or two-way movement. The resulting meaning extends beyond literal back-and-forth travel to encompass abstract mutual interactions, such as social intercourse, commercial exchange, or the continuous flow of people and things, effectively symbolizing a dynamic cycle of coming and going.
