"Yugong Moving Mountains" is a fable story of the ancient Chinese Han nationality. It is selected from "Liezi Tangwen", by the imperial aggressors of the Spring and Autumn Period and the Warring States Period.
"Yugong Moves Mountains" tells the story of Yugong who fears hardships, perseveres, digs mountains and finally moves the mountains away by touching the Emperor of Heaven.
There were two mountains in front of Yu Gong's house. He was determined to level them down. Another wise man laughed at him for being too foolish to think he could. Yu Gong said, "I have sons dead, sons dead and grandsons. There are endless descendants. Why should I worry about unemployment?" Afterwards, he moved the Emperor of Heaven, so the Emperor ordered his two sons to move two mountains

英文版愚公移山简写加注解？
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.
太行，王屋二山的北面，住了一个九十岁的老翁，名叫愚公。 二山占地广阔，挡住去路，使他和家人往来极为不便。
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?"
一天，愚公召集家人说：「让我们各尽其力，铲平二山，开条道路，直通豫州，你们认为怎样?」
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?"
大家都异口同声赞成，只有他的妻子表示怀疑，并说：「你连开凿一个小丘的力量都没有，怎可能铲平太行、王屋二山呢?况且，凿出的土石又丢到哪里去呢?」
"Dump them into the Sea of Bohai!" said everyone.
大家都热烈地说：「把土石丢进渤海里。 」
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.
于是愚公就和儿孙，一起开挖土，把土石搬运到渤海去。
Now Yugong's neighbour was a widow who had an only child eight years old. Evening the young boy offered his help eagerly.
愚公的邻居是个寡妇，有个儿子八岁也兴致勃勃地走来帮忙。
Summer went by and winter came. It took Yugong and his crew a full year to travel back and forth once.
寒来暑往，他们要一年才能往返渤海一次。
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."
住在黄河河畔的智叟，看见他们这样辛苦，取笑愚公说：「你不是很愚蠢吗?你已一把年纪了，就是用尽你的气力，也不能挖去山的一角呢?」
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.
愚公叹息道：「你有这样的成见，是不会明白的。 你比那寡妇的小儿子还不如呢!就算我死了，还有我的儿子，我的孙子，我的曾孙子，他们一直传下去。 而这二山是不会加大的，总有一天，我们会把它们铲平。 」
The wise old man was totally silenced.
智叟听了，无话可说：
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.
二山的守护神被愚公的坚毅精神吓倒，便把此事奏知天帝。 天帝佩服愚公的精神，就命两位大力神背走二山。
进化树怎么看？
首先来学习一下系统发育树的基本结构。故名思意，系统发育树具有与树类似的结构：
最基部为根节点（root）。有的树有，有的树没有。
从根开始生长，每次分出两条枝（branch）。
枝生长到一定程度后，再次分枝的地方称为内节点（internal node）
树的最末端称为叶节点（leaf），有时候也叫tip。
包含多个叶节点的分支称为进化枝（clade）。
以上是树的基本结构。如果只有这些结构，还不能称其为系统发育树，只能说是一个树状图。只有当我们赋予该树状图以生物学意义的时候，才能称为系统发育树：
一个叶节点代表一个生物类群（taxon），如人类。
一个内部节点代表一个假想的祖先（ancestor）。这个祖先在历史中存在，但往往已经灭绝。为什么要加上“假想”，是因为我们没有确切的证据去证明这个祖先到底是什么。人类、倭黑猩猩、黑猩猩的汇集处代表这三者的共同祖先，由于这个节点距离这三个类群最近，所以把该节点称为这三个类群的最近共同祖先（Most Recent Common Ancestor, MRCA）。与祖先对应的词汇是后代（descendants）。
枝的长度用于衡量祖先和后代之间的远近。根据树的构建方法不同，枝的长度可以有不同含义。如果使用基于进化模型的方法（贝叶斯法/最大似然法），枝的长度代表碱基替换速率。如果使用基于距离的方法则代表的是距离。因为用于构树的性状、构树的方法对枝长影响很大，所以不同的树之间的距离往往无法直接比较。有些系统发育树的枝长会被忽略掉，此时枝的长度是没有意义的。
根节点代表所有类群的共同祖先。不是所有系统发育树都是有根的，没有根的系统发育树称为无根树。
除了以上基础结构，有的系统发育树还包含以下内容：
支持度：内部节点有时候会有一个数字，称为支持度（support value），用于代表该分支结构的可靠程度。值的大小在0%-100%之间。和枝长一样的是，支持度也有不同的计算方法，如普通的bootstrap value、Ultra fast bootstrap、后验概率等。值越大，说明越多证据支持该分支。
外群/外类群（outgroup）：目标类群之外的类群。如果我们的目标类群是人类和黑猩猩，那么可以选用大猩猩来作为外群。外群一般用于给系统发育树赋根，赋根之后我们才能从进化树上看出演化的先后顺序。
演化时间：如果能够找到明确的历史记录或者化石证据，确切地知道某个已经灭绝的物种曾经存在的时间，就可以用于校正系统发育树的时间。经过校正的系统发育树有时候称为time tree。
