"By placing it higher, everyone can save a lot of effort. When we build a sluice, just open it when you need water. There's no need for everyone to carry water in buckets every day."
Lin Caisang explained.
"During the dry season, it's hot. It's not ideal for each household to carry water every day. Besides, overheating could lead to heatstroke. Look, I've drawn ditches here, and they lead to each household. When the sluice is opened and water is released, it will flow directly into these ditches.
By using water in this way, everyone doesn't have to work so hard and can conserve energy for other things. Isn't that great?"
During the dry periods in Yejun, that's precisely when the men from their village go up the mountain to collect cubilose or forage for wild goods to sell in the town for silver. This factor must be taken into consideration.
