Top:chana-side. pingshang is the place where i was totally beated by the lonliness being alone without anybody who can communicate verbally. so i stayed more days at pingshang to challenge against the loniness. i guess this slight courage would make big difference on mental strength not to be crazy. Bottom:vietnam-side. with a friendly guy who invited me to stay his house. this small towm where i don't have map, local money, and the ability to see signboard and communicate with people. it was pretty hard to find money exchange place.
