Wu Zixu
Prince Guang was the son of King Yumei, and the nephew of King Liao. He welcomed the Chu exile Wu Zixu into his entourage and, when he sought to usurp the throne of Wu, was introduced by him to Zhuan Zhu. Zhuan assassinated King Liao in 515BC and the prince became King Helü. The king assigned Wu Zixu to lead the design and building of his "great city," which forms the basis of Suzhou's present old town.
