Is “King Zhuang of Chu did not attend to state affairs for three years after ascending the throne, comparing himself to 'a bird that soars in one flight and startles the world with one cry.'” true?

According to the Records of the Grand Historian, 'The Hereditary House of Chu', Wu Ju admonished King Zhuang with a riddle: 'For three years, it has not flown or sung.' The king replied, 'Though it has not flown for three years, when it flies, it will soar to the sky; though it has not sung for three years, when it sings, it will startle the world.' (The 'Biographies of the Jesters' in the same work attributes this saying to King Wei of Qi, but the mainstream follows the 'Hereditary House of Chu'.)
