"As the wooden cart turns, it will bring up some water, and once enough accumulates, the weight will press down."
"Then this water jug will tip over, emptying completely, and once it's empty inside, it will be lifted back up."
"Each time the water jug tips, it will alternately hook those gourds beside it, pouring the medicinal ingredients inside into the concoction."
"This will save you a lot of effort, old sir, and you won't have to keep watch over it constantly."
