Let’s go back a century before when Indonesia is in age of colonialism.
Elementary school always tell student that Indonesia fought the Colonialist by “bambu runcing”.
So what is “bamboo runcing” ?
“Bambu runcing” is weapon that made from bamboo. They sharpened the bamboo so it can be deadly weapon. The function is like spear. It wounded the target by piercing them.
They must be brave because their enemy is rifle.
