Who terrorized the China seas?

Chang Yih was a small hunchbacked Chinaman. He sailed on short pirate raids around the coast of China. He became very rich, and his fleet of stolen boats grew until he owned five hundred.

When Chang Yih was killed in a typhoon, his wife took charge of the fleet. She was even fiercer than her husband. Once she defeated a hundred ships belonging to the Emperor of China. Chang Yih’s wife rewarded her pirates with silver for each victim’s head that they brought her.
