Hello Liu Lian!
Sorry it took me so long to respond. Level 3 Japanese is extremely difficult and always busy. It’s nothing like level 1 and 2. Also, I have been working more, going to the gym and doing Aikido. So maybe I am trying to kill myself or something, but it seems like all free time has disappeared.
Most excellent essay and very interesting. Unfortunately I cannot give you any ideas about abbreviations with your extremely specific “esoteric” subject. Entry essays are also extremely difficult for me or anyone trying to enter a prestigious graduate school in the United States. The only thing I can do is wish you a very hardy “Good Luck!” The only thing I would be able to help you with is grammar mistakes if you wish.
So GOOD LUCK Liulian. I have faith in you and know you can do it. Let me know if you would like me to help you with the grammar aspect.
