长（chang）
Name meaning
长 (chang) on this page is read cháng, not zhǎng. It means long in distance or duration, lasting, or far-reaching. In naming it can suggest endurance and breadth, but the multiple readings make pronunciation guidance essential.
Practical naming use
长 (chang) offers an old, expansive image of duration, distance and endurance. It can feel literary and masculine, but it is less straightforward in a modern given name because readers may choose another pronunciation.
Use 长 (chang) in a familiar compound whose context fixes the cháng reading and adds a human quality rather than leaving the character isolated.
