put on, twist around
繚 centers on wrapping or winding something around: putting on clothing by wrapping it around the body, or twisting a cord around an object.
繚 combines 糸 (thread) with 尞, which likely contributes the sound and the idea of encircling or winding. The exact historical development of 尞 is uncertain.
The left side 糸 is thread, and the right side 尞 looks like a complex wrapping shape. Picture thread being twisted around and around something until it is fully wrapped.
For リョウ, imagine a long thread wrapping around a row of objects: row -> リョウ, and the thread twists around each one.
