The word 成交 is formed through a conceptual combination of its two constituent characters: 成 (chéng), which carries the meaning of "to complete", "to succeed", or "to bring to fruition", and 交 (jiāo), meaning "to hand over", "to deliver", or "to exchange". Together, they create a single idea that visually and notionally represents the final, successful moment of a transaction where an agreement is completed and the items or considerations are formally exchanged between parties, thus capturing the entire essence of "striking a deal" or "concluding a sale" in one compact term.
