Chinese names are usually short — most have two or three characters. In Chinese, the family name comes first and the given name comes after, which is the opposite of English. For example, 王大衛 (Wáng Dàwèi): 王 is the family name, 大衛 is the given name. In English we'd say "David Wang," but in Chinese we say 王大衛. Tap the speaker icon next to each example to hear it.
Many Chinese family names are only one character, such as 王, 林, 李, and 陳. Given names, on the other hand, often carry a meaning the parents chose — either a quality they hope for, like 安 (peace) or 樂 (happiness), or an image from nature, like 雨 (rain), 月 (moon), or 星 (star).
If you're learning Chinese, you can choose a Chinese name too. It can sound like your English name, or it can carry a meaning you like. A good Chinese name doesn't need to be difficult — it just needs to be easy to say, easy to remember, and meaningful to you.
