cast pearls before swine
    During the Warring States Period, there was a musician named Gongming Yi, who playedmusical instruments very well.
    There were a great number of people fond of listening to him play, and respected him very much.
    One day, Gongming Yi saw a cow when he was having fun in the countryside.
    He thought, "Everybody compliments my music. Why don't I play some music for this cow?"
    He played a piece of elegant quaint music for the cow, but the cow just kept grazing the grass with its head down.
    He played another piece of joyful music, but the cow still kept its head down to graze the grass and totally ignored him.
    Gongming Yi was so disappointed and started to question his ability.
    A passerby said to him,"It's not because your ability is bad. It is because the cow can not understand music at all."
    對(duì)牛彈琴
    戰(zhàn)國(guó)時(shí)代，有一個(gè)叫公明儀的音樂(lè)家，他很會(huì)彈琴。
    很多人都喜歡聽(tīng)他彈琴，人們很敬重他。
    一天，公明儀在郊外游玩時(shí)，看到了一頭牛。
    他想：大家都贊揚(yáng)我的琴技，不如我給牛也彈一曲吧!
    他給牛彈奏了一曲古雅的曲子，牛埋頭吃草不理他。
    他又彈奏了一曲歡快的曲子，牛依然埋頭吃草不理他。
    公明儀拿出自己的全部本領(lǐng)， 結(jié)果牛還是不理他。
    公明儀非常失望，開(kāi)始懷疑自己的琴技。
    路人說(shuō)：“不是你彈的琴不好，而是牛根本聽(tīng)不懂啊!”
