+愚公移⼭山
+太⾏行行，王屋⼆二⼭山的北北⾯面，住了了⼀一個九⼗十歲的⽼老老翁，名叫愚公。⼆二⼭山佔地廣闊，擋住去路路，使他
+和家⼈人往來來極為不不便便。
+⼀一天，愚公召集家⼈人說：「讓我們各盡其⼒力力，剷平⼆二⼭山，開條道路路，直通豫州，你們認為怎
+樣？」
+⼤大家都異異⼝口同聲贊成，只有他的妻⼦子表示懷疑，並說：「你連開鑿⼀一個⼩小丘的⼒力力量量都沒有，怎
+可能剷平太⾏行行、王屋⼆二⼭山呢？況且，鑿出的⼟土⽯石⼜又丟到哪裏去呢？」
+⼤大家都熱烈烈地說：「把⼟土⽯石丟進渤海海裏。」
+於是愚公就和兒孫，⼀一起開挖⼟土，把⼟土⽯石搬運到渤海海去。
+愚公的鄰居是個寡婦，有個兒⼦子⼋八歲也興致勃勃地⾛走來來幫忙。
+寒來來暑往，他們要⼀一年年才能往返渤海海⼀一次。
+住在⿈黃河河畔的智叟，看⾒見見他們這樣⾟辛苦，取笑愚公說：「你不不是很愚蠢嗎？你已⼀一把年年紀
+了了，就是⽤用盡你的氣⼒力力，也不不能挖去⼭山的⼀一⻆角呢？」
+愚公歎息道：「你有這樣的成⾒見見，是不不會明⽩白的。你⽐比那寡婦的⼩小兒⼦子還不不如呢！就算我死
+了了，還有我的兒⼦子，我的孫⼦子，我的曾孫⼦子，他們⼀一直傳下去。⽽而這⼆二⼭山是不不會加⼤大的，總有
+⼀一天，我們會把它們剷平。」
+智叟聽了了，無話可說：
+⼆二⼭山的守護神被愚公的堅毅精神嚇倒，便便把此事奏知天帝。天帝佩服愚公的精神，就命兩位⼤大
+⼒力力神揹⾛走⼆二⼭山。
+How The Foolish Old Man Moved Mountains
+Yugong was a ninety-year-old man who lived at the north of two high
+mountains, Mount Taixing and Mount Wangwu.
+Stretching over a wide expanse of land, the mountains blocked
+yugong’s way making it inconvenient for him and his family to get
+around.
+One day yugong gathered his family together and said,”Let’s do our
+best to level these two mountains. We shall open a road that leads
+to Yuzhou. What do you think?”
+All but his wife agreed with him.
+“You don’t have the strength to cut even a small mound,” muttered
+his wife. “How on earth do you suppose you can level Mount Taixin
+and Mount Wanwu? Moreover, where will all the earth and rubble go?”
+“Dump them into the Sea of Bohai!” said everyone.
+So Yugong, his sons, and his grandsons started to break up rocks and
+remove the earth. They transported the earth and rubble to the Sea
+of Bohai.
+Now Yugong’s neighbour was a widow who had an only child eight years
+old. Evening the young boy offered his help eagerly.
+Summer went by and winter came. It took Yugong and his crew a full
+year to travel back and forth once.
+On the bank of the Yellow River dwelled an old man much respected
+for his wisdom. When he saw their back-breaking labour, he ridiculed
+Yugong saying,”Aren’t you foolish, my friend? You are very old now,
+and with whatever remains of your waning strength, you won’t be able
+to remove even a corner of the mountain.”
+Yugong uttered a sigh and said,”A biased person like you will never
+understand. You can’t even compare with the widow’s little boy!”
+“Even if I were dead, there will still be my children, my
+grandchildren, my great grandchildren, my great great grandchildren.
+They descendants will go on forever. But these mountains will not
+grow any taler. We shall level them one day!” he declared with
+confidence.
+The wise old man was totally silenced.
+When the guardian gods of the mountains saw how determined Yugong
+and his crew were, they were struck with fear and reported the
+incident to the Emperor of Heavens.
+Filled with admiration for Yugong, the Emperor of Heavens ordered
+two mighty gods to carry the mountains away.
