The family wealth of thirteenth ancestor Wu Churen (1242- 1304) was such that his father was targeted by soldiers of the Mongol Yuan Dynasty. When the soldiers captured Wu’s father, they demanded that he shout across the mountain to his family for help. They wanted him to order his sons to come and ransom him with silver. Wu Churen hurried before the general, saying “I’m the one who hid the silver, so please let me go and fetch it to redeem him”. But when he got to the cellar, he found that the silver had been taken, and so returned to the Mongol general and declared, “The silver is no longer there, so I am bringing my head instead, in place of my father”. His younger brother Wu Yuan also pleaded with his life to save his father. The soldiers were so shocked by their spirit of self-sacrifice they finally released all of them.
