译文：不要和他人争长短与得失，只求自己能增长知识和才干。赏析：我们在与人交往之中，少谈论别人的是非，少和别人争长短。不管是赢了还是输了，有什么用呢。与其和别人争论毫无关系的事情，不如静下心来多读书学习，多反思自己的言行，或许能收获很多知识。
Every one is their God,if you give up on yourself,who else will save you?Every one is busy,some are busy livig,some are busy dying,and you, who are busy chasing fame and fortune,who are busy with daily necessities,try to stop to think a second:if your brain has been institutionalized?Where is your God?
