long, leader, superior, senior
長 centers on extended physical length and the social extension of that idea: a person who stands out as a leader, superior, or senior figure.
長 is a pictograph of a person with long hair, symbolizing length and by extension an elder or leader. The modern form retains the elongated shape.
The character looks like a tall figure with flowing hair, suggesting something long. A long-haired person in a group often stands out as the leader or senior.
For チョウ, imagine a long queue of people waiting to see the leader: queue -> チョウ, and the leader is at the front of the long line.
