As we have direct buses from Ansan to Hamyang, I've been through this Hamyang bus station over a half-dozen times in my exploration of the north-east sections of the Chirisan Doollae-Gil. I'll pass through here for Section 9 and then will have to pick another base for exploring the subsequent sections further south.
In photo #3, it's clear what this bus driver's pet peeve is. The sign near the bottom-right: "Don't chew gum noisily."
