climbing plants, vines, cane
籘 centers on long, flexible plant growth: climbing plants, vines, and cane-like stems that twist or trail.
籘 is a rare character combining 竹 (bamboo) with 縢, which likely contributes the sound and relates to binding or wrapping, suggesting a plant that climbs by twining like bamboo or cane.
The bamboo top 竹 suggests a plant with jointed stems, and the lower part 縢 looks like threads wrapping around. Picture a vine climbing a bamboo pole, its tendrils twisting like thread.
For トウ, imagine a long vine reaching toward a tall tower: tower -> トウ, and the vine climbs up the tower like a cane.
