I'm looking for the name of a book I read three years ago (although it was published in the early 2000s maybe) about a boy who leaves his village and goes to a large city. The cover art is a corner of Bruegel's Tower of Babel artwork where men are discussing things at the foot of the tower. The part I'm referring to is the banner of this webpage.

Once the boy arrives at the city I believe he befriends some beggars who fake illnesses. He then eventually becomes a painter's apprentice, before being forced to leave the city, and returns to his village with (this is a very specific part I remember) a handful of nutmegs. This is nutmegs as in the spice, whole nutmegs.
I also remember the name of the book being the name of the boy who is the main character. The author was almost certainly male. I believe the story ends with the boy growing old and regretting returning to the village with only nutmegs. It is not Senlin Ascends.
I have been searching for a year now. Is there anyone who has ever heard of any book like this and could point me to the title?
