Chess Sage Battle
When Qing Wuzi was young, his family was poor and he'd sneak to a private school to listen to the teacher teaching, wanting to learn a few words. However, he ended up seeing the teacher playing chess and since then, he had become infatuated with it.
Regardless of whether he was chopping firewood, grazing the cattle, or farming in the fields, Qing Wuzi was constantly pondering about chess. He couldn't afford to buy a chessboard so he drew lines on the ground and used stones as pieces.
He didn't have an opponent, so he split his attention into two, playing his left against his right.
To temper his chess skills, he ground himself a chess set and then set up a stall in town. For those who could win against him in a game, he'd work for them for free for a month.
Therefore, those landlords and wealthy merchants who were bored and also wanted to take advantage of him came and played against him.
Qing Wuzi won against all of them.
