5. History
Liushu category: Compound ideogram (会意)
Origin: Originally depicted a sack or a bundle of wood (木) tied around the center with a cord to hold it together.
Semantic Evolution: From 'tying wood into a bundle' it generalized to 'any bundle or bunch', then to 'tying up/binding', and finally extended to abstract control and as a classifier for beams of light or bundles of items.
The character clearly preserves its ancient pictographic roots of a cord wrapped around a stack of sticks.
