With this velocity model and broadband records from 5 CDSN stations, we inverted focal mechanisms of Chifeng earthquake on August 16th, 2003 with the "Cut and Paste" method. Then we confirmed focal depth and the source mechanisms by comparing synthetic body waves at teleseismic distance with broadband records of 9 IRIS stations. Our result shows that the best double couple solution of this M w5.2 event is 315°, 64° and 19°for strike, dip and slip angles respectively, the second nodal plane solution is 216°,74°, and 152°. The focal depth is 25±2 km, suggesting that this quake occurred in the lower crust which is much deeper than most continental earthquakes.

Because lecturer Wang always saying it recently, should sublease the apartment with us, and I call him uncle Wang according to the courtesy , focal point even if I want classics of watching, I extraordinary fearness household noisy, household noisy I nothing hear right away, so I must depend on Triratna, because the uncle Wang he become a Buddhist at all, what he believes is the Triratna that is always said, explain Buddha dharma to him, he will talk about the similar law that they always said, so really make me too bitter to say, certainly I know this it is hindered that is my family property, if miss obstacle, must learn to give up, that is to say that gives up one's own moral integrity , certainly perhaps a lot of people can not understand , in fact very simple , a reason for my meaning, what the string is fastenned is too tight, very apt to lose brokenly, the ones that fastenned are too too loose to spring the sound, so adjust just now very all right, what I say certainly it gives up to be Buddha Bodhisattva in the degrees of all living creature, can give up heads with the brain , certainly if you meet the greedy person , or ignorant person, the left eye of your charity, he wants the right eye, you are two holes of charity, even if he throws your eyes to the ground to step on rottenly , it is so discredited that will blurt out and scold and say, so say that you know , cross all living creature's thing , it is not really what common people can do in this, so I must have pieces of view think meet as me wholehearted to ask people of law , I willing charity everything certainly, but if the other side does not ask the law wholeheartedly , certainly the charity that I can not be silly and silly, I must do the view with reason , it is all right that I act dumb with him, that is to say that he acts dumb with me in meaning, I certainly can regard oneself as noble-minded and unwilling to swim with the tide too, Buddha Bodhisattva is it cross some three evil all living creature of dish to want sometimes, must put down the figure , go to put into animal's body , then go to follow the statement of one of three evil , the focal point is that I am not so great, I do the part of Theravada well first , or finish humanity first, ten is it do five exhortation well to good at first, three Ban 5 exhortation make and discuss well that Bodhisattva has feet to give up to give up, three Ban five exhortation finish anyway, you is it defend the doctrine god defend , so I it hopes to be too urgent what oneself force to have, I am only relaxed studies Buddha.

最近因为一贯道的王讲师，要跟我们分租公寓，而我也是依照礼数称他王叔叔，重点就是我要看经典，我非常的怕人家吵，人家一吵我就什麼也听不到，因此我必须要依靠三宝，因为这位王叔叔他根本没有皈依三宝，他所信的是一贯道的三宝，跟他讲佛法，他都会讲到他们一贯道的相似法，因此真的让我有苦说不出，当然我也知道这都是我的业障，如果不想被障碍，就必须要学会舍，也就是说舍掉自己的德行，当然我的意思可能很多人会听不懂，其实很简单，就是一个道理，弦旋的太紧，很容易断掉，旋的太松会弹不出声音，因此就是调的刚刚好就好，当然我所说的舍就是佛菩萨度众生的时候，可以舍掉头目随脑，当然如果你遇到贪心的人，或者愚昧无知的人，你布施左眼，他要右眼，你两眼都布施，他就是把你的眼睛丢到地上踩烂，还会随口骂说这麼臭，所以说这你才知道，渡众生这一件事情，真的不是一般人可以办到的，因此我必须要有个观想，当我遇到真心求法的人，我当然愿意布施一切，但是如果对方不是真心求法，当然我不可能傻傻的布施，我必须要随缘做观，我跟他装傻就好，意思就是说他跟我装傻，当然我就是不能太自命清高，有时候佛菩萨要渡一些三恶道的众生，都必须要放下身段，去投入畜生身，然后去跟三恶道的说法，重点就是我没有那麼伟大，我先把小乘的部分给做好，或者先把人道做好，先把五戒十善做好，三皈五戒做好再谈菩萨戒具足戒，反正三皈五戒做好，你就会有护法神守护，因此我不希望把自己逼的太紧，我只要轻松的学佛。
