yellow dragon
彲 refers specifically to a yellow dragon, a mythical creature. The meaning is narrow and does not extend to other concepts.
彲 combines 麗 (beautiful, elegant) with 彡 (hair, bristle), likely describing the ornate, flowing mane or whiskers of a dragon. The exact historical development is uncertain.
The left side 麗 suggests something beautiful and ornate, while the right side 彡 looks like flowing hair or whiskers. Together they paint a picture of a magnificent yellow dragon with elegant, flowing whiskers.
For チ, imagine a yellow dragon drinking tea (チ) from a giant cup, its whiskers dipping into the brew.
