Carrying two stones at a time is this heavy.
Most of the stones he used weighed less than thirty jins. Anything heavier would be unnecessary.
Walking with twenty jins of stones on his back was a breeze, but holding them wasn't very practical and could tire him out easily.
He made some modifications to his basket, mainly to make it softer so it wouldn't rub against his shoulders and back.
His daily workload was measured by the time and his level of fatigue.
Carrying stones was never an easy task.
On the first day, his arms hurt a lot, and his legs felt weak.
He didn't know how many trips he had made.
He suspected that his count of the stones used was wrong. It seemed like building the wall didn't require that many stones.
Moving stones during the day and stacking them at night.
He planted two branches by the wall. He placed two horizontal logs on the branches, securing them, leaving them half a meter above the ground. Standing on them allowed him to stack the wall higher.
