成（cheng）
Name meaning
成 (cheng) means to become, complete, accomplish or bring something to success. In a given name it should suggest fulfillment through steady effort, not a guarantee of success.
Practical naming use
Use 成 (cheng) when the name should feel constructive, reliable and achievement-oriented. It suits study, craft, business, public service, engineering or a person expected to complete what they begin. Pair it with a value that gives success a human direction.
Pair 成 (cheng) with characters such as 成安 (Chengan) Cheng'an, 成文 (Chengwen), 成德 (Chengde) or 成远 (Chengyuan). Avoid pairing it with a word that makes the name sound like a slogan of success.
