Notes
From a story about Nanguo(南郭), a terrible [reed mouth organ>(竽) player, who lived during the Warring States period of China. At the time, King Xuan of Qi(齊宣王) loved to hear concerts by groups of people 300 large. so Nanguo could arbitrarily(濫) play whatever, and there was a sufficient(充) number(数) of people to cover him. However, the next ruler, King Min of Qi(齊湣王), preferred solo performances, and so Nanguo fled.
