濫竽充數

King Xuan of the state of Qi liked enjoying yu（an ancient wind instrument consisting of reed pipes）. He insisted on three hundred musicians playing together. Nanguo， an educated man in retirement， asked for permission to play yu for the king. The king graciously gave his consent and Nanguo received the same salary as the other several hundred musicians.

After the death of king Xuan， king Min became the ruler of the state of Qi. He liked to listen to the musicians playing one by one. Nanguo fled.

回答下列問題：

1. Who was Nanguo?

2. Why did Nanguo flee?

3. Can we learn something from Nanguo?

(1) instrument n. 器具

(2) consent n. 同意，贊同

(3) salary n. 俸金，俸祿

齊宣王喜歡聽樂師們吹竽（一種中國古代樂器的名稱，很像現在的笙）。他總是要三百個樂師一起吹竽。南郭先生（處士：沒有官職的普通知識分子）請求為國王吹奏，國王高興地答應了。并且他的年俸祿和其他樂師一樣。

齊宣王死后，齊泯王繼位。齊泯王喜歡聽樂師們單獨吹奏。南郭先生嚇跑了。
