Long Gang had completely failed to realize just how smart his brother, only five years younger than him, was.
When they worked together, Long Gang would walk behind during their uphill climb which caused the weight to slide towards him, leaving him breathless like an ox while his brother seemed unaffected. Coming downhill, his brother let him walk in front, putting him behind again allowing the weight to shift back towards him, making him even more tired while his brother relaxed.
Back at home, still gasping for breath, his brother had already efficiently taken care of the pig grass and firewood they had carried down from the mountain.
At this point, their parents only saw his incompetence, thinking the extra years of food he ate were wasted like feeding a pig.
His brother was clever, clever enough to anticipate the parents' thoughts and react accordingly.
