How to Write 洙 (zhū) — Meaning “Zhu (name of a river)”

Imagine the Zhu River (洙) as a body of water (氵) that flows near the old home of the philosopher Zhu Xi (朱). The "red" meaning of 朱 can also remind you of the river's muddy reddish color. This visual link between water and the surname Zhu helps fix the character in your mind.

First write the three strokes of the water radical (dot, dot, lift) neatly on the left. Then write 朱: start with a left-falling stroke (撇), followed by horizontal, vertical, another left-falling, and finally a right-falling stroke (捺). A common mistake is to write the vertical stroke of 朱 too long or to place the water radical too far from the right part.

洙 (zhū) has 朱 on the right, while 㳄 (xián, meaning saliva or to yawn) uses 欠 on the right, and 汧 (qiān, a river name) uses 开 on the right. Visually, the right-side components are distinct: 朱 looks like a vertical stroke with two horizontal lines, 欠 is open at the bottom, and 开 has two horizontal strokes. Their meanings are also unrelated: 洙 is a specific river, 㳄 relates to saliva, and 汧 is another river name.

洙 is rarely used by itself today; it mainly appears in place names like 洙水 (Zhu River) and the classical term 洙泗 (Zhu and Si Rivers). These two rivers are strongly associated with Confucius, who taught near them, so 洙泗之风 refers to the Confucian tradition. The character carries a scholarly, historical flavor and is most often encountered in classical or academic contexts.

Common words containing 洙 include: 洙泗 (zhū sì) — Zhu and Si Rivers (associated with Confucianism); 洙水 (zhū shuǐ) — Zhu River; 洙泗之风 (zhū sì zhī fēng) — The Confucian tradition / The style of Zhu and Si.
