When Su Song (1020-1101) was Governor of Wuzhou, his mother, Lady of the Wei Realm, boarded a boat to visit him at his place of work, and the gentleman had set out to meet her. While going upstream on the Xiang River, they encountered a rapid torrent, and the boat turned side-on to the flow and threatened to capsize. The gentleman cried out, and without fear of the water swam out to save her. Before long, the boat suddenly recovered its alignment, allowing the lady to climb onto the bank. It then capsized. It is certain that, moved by his earnest filial piety, the spirits acted to shield and support her; this is the only explanation of this occurrence.
