"My greatest accomplishment is receiving a perfect Australian Tertiary Admissions ranking of 99.95."
Beijing-born medical student Yiran, 19, is a big fan of chemistry.
"I find it interesting how substances interact with one another, change colours or composition," says Yiran.
"It's directly relevant to my current study of medicine and has widespread applications which can be incorporated into elements of biology and mathematics."
Diligent, honest and friendly, Yiran is a big believer in hard work, a lesson he would like to teach the Beauties while in the house.
"No matter how intelligent you are, applying yourself to the task at hand is the key to success. I think I can teach my partner the importance of perseverance, something which has carried me all through my academic achievements," he says.
Yiran is hoping to learn more about girls when in the mansion as his only kiss so far was won in a game of Truth or Dare while on summer camp in Beijing.
"I was lucky, my dare was to kiss a girl I chose," he says.
Yiran's ideal girlfriend would be "a good person, who cares for others, is relatively intelligent and shares similar interests with me".
Most of Yiran's spare time is taken up either playing, or coaching badminton, studying, or raising money for an orphanage in Cambodia. In the past two years he has donated $4000 by setting up study seminars for aspiring students seeking admission into medicine.
"The seminar was taught by high achieving medical students with a passion for philanthropy. My high school was generous enough to support our initiative by providing us with the venue. 100 per cent of what I earn from the study group goes directly to charity."
