用英語說成語:畫餅充饑（雙語）

In the Three Kingdoms Period (sān guó 三國時代,220-280AD), the king of the state
of Wei (wèi guó 魏國), Cao Rui (cáo ruì 曹睿), wanted to select a very capable man
to work for him. He said to his ministers: "When choosing a talented person,
always beware of one with a false reputation. A false reputation is just like a
picture of a cake; it can' t relieve hunger."

Later, this idiom came to be used to mean comforting oneself with unrealistic
thoughts, without solving practical problems.

三國時代魏國的皇帝曹睿，準備選拔一個有才能的人到朝廷來做官。曹睿對他的大臣說：“選擇人才，不能光找有虛名的人。虛名好像是在地上畫的一塊餅，只能看，不能解決肚子饑餓的問題啊!”
后來人們就用“畫餅充饑”這個成語比喻用空想安慰自己，不能解決實際問題。
