Everything in a cemetery is unusual to me lol! I forgot to ask the lady if the pots are for sale but I think it was not. I didn't notice pots anywhere else in the market at least where we walked around. The river is indeed peaceful. We were warned not to go further up as it is deep and dangerous.
Thanks @erikah!
You're right, rivers can be dangerous as you never know how deep the water is and it can be whirlpools that can swallow you in a split second.
