What did Emperor Liu Yong say?

Liu Yong (A.D.1719-1804) was a scholar in the Qianlong period of the Qing Dynasty, with profound knowledge and brilliant talents. One day, Emperor Qianlong came up with a difficult problem, which puzzled Liu Yong. He first asked him, "How many people go out through the nine gates of Shi Jing every day? How many people came in? " Liu Yong held out two fingers and said, "Two people!" Gan Long asked, "Why are there only two people?"

Liu Yong said, "Your Majesty, I'm not talking about two people, but two kinds of people: one is a man and the other is a woman, isn't it?" Seeing that Liu Yong was not stumped, Gan Long asked, "How many people did you say died and died in a year in Qing Dynasty?" Liu Yong replied: "One is born every year, and twelve people die." Gan Long pretended to be surprised: "According to you, no one!" Liu Yong said: "Long live the echo, I said it according to the zodiac. For example, this year is the Year of the Ox. Whether it is100000 or 300000, it belongs to cattle, so it is said that only one is born every year. However, in a year, there are all kinds of people who die, so twelve people die a year. " Emperor Qianlong was overjoyed after hearing this, and he valued Liu Yong more from now on.
