feudal state which existed BC 700-469, now in Shandong
邾 is a historical proper noun referring to a small feudal state that existed in ancient China, located in what is now Shandong province. It has no common standalone meaning beyond this specific historical reference.
邾 combines 朱 (likely a phonetic component) with the city/walled-town radical ⻏, indicating a place name. The exact historical development is uncertain, but it is a typical phono-semantic compound for an ancient state name.
The left side 朱 (vermillion) and the right side ⻏ (city wall) together suggest a named place. Think of a vermillion-walled city that was once the feudal state of 邾.
For チュ, imagine a tiny feudal state whose name sounds like 'chew'—as if the city walls are being chewed by time. Chew -> チュ, and the ancient state is slowly worn away.
