AS A PEOPLE SUFFERED A LOT IN APPLICATIONS AND AT LAST GOT WHAT I 
WANT, I'D LIKE TO SHARE SOME OF MY EXPERIUENCES AND IDEAS IN 
RECOMMENDATIONS , TO HELP THOSE HONORABLE NEW COMERS, AND THOSE WHO ARE 
SEPARATED, BY ANY REASON , LIKE MY WIFE AND ME. 
In my opinion, the most important thing in application differs much from 
people people, from school to school. But generally speaking, they will 
consider all the materials they have and at last, if there ARE STH VERY 
OUTSTANDING CONCERNING you, they will surely give you what you want. 

Among the most important things, including recommendaiotns, transcripts, 
score in GRE and Tofel, the most common standard is that TRANSCRIPT, TOFEL, 
GRE SUB, GRE GENERAL, then the recommendation. 

The recommendation becomes the most trivial thing in this procession is 
because: 
(1) USA professors seems already know that few letters were written by 
faculty members, they are always the work of students'. 
(2) There are few professors in china which are famous and willing to write 
recommedations for students who is going out. 
(3) Most professors are not so famous as to be useful in deciding the 
students' being admitted or not. 

But we have some exceptions here. When you are lucky enough to find a 
famous professor, famous to be known by many professors in USA, Acedamy 
members are not enough in this issue though. To provide a instance, like 
Zhang Dainian, Chen daisun, or Zhou Guangzhao, or some people who are very 
close friend or holding close relations with the professors you are 
applying, these peoples recommendations will be extremely useful. 

Anyway, the recommendations are required in the applications, so we need to 
choose the recommendations and the people to write it. There are 6 kinds of 
recommendations, each is worse then the next one. 

(1) Letters written by you, signed by famous professor or professor closely 
related to the school you are applying; 
(2)Letters written by you, corrected by those people as refered above; 
(3)Letters written by you, signed by common faculty professors; 
(4)letters written by you, corrected by those people as above; 
(5)Letters written by famous people and you have no access to it; 
(6)Letters written by common ones. 

Choose you letters in the order above, and there are many sad experiences 
concerning the case against this basic rule: I was refused by 4 top schools 
just because I have used a very famous academy memeber's four reference 
letters. There are many other skills concerning the resume, etc. which I 
will cover next time. I guess as a conclusion, to make your reference 
letter useful, you must,
(1) Make totally good words in it, or make it more realistic, put sth. bad 
but not improtant at all; 
(2)Choose relevant people to write it, either they do not know, or they 
know very well, Academy member in other fields will equals to common ones, 
or even worse because you can not get good words from them generally 
speaking.
