A young man meets an old man on the way to Ise, and promises to visit his village. A boatman saves a blind man from a flood, but the blind man dies. A rich man has a very powerful servant.  The servant is smart, too, so the rich man gives him one challenge after another.
Since you would cry when you did it,

El trabajo era tan duro

Como era comum as pessoas chorarem
fazendo isso, era chamado de pilão do choro.
