It happened just after 11:00 p.m. Friday night on the 1400 block of Sloan Way.
The female victim, who does not want to be identified, still fears for her safety.
"The thing that kept running through my mind was I might die tonight," she said.
Police say four masked men, three of them armed, walked into her bedroom looking for jewelry and cash.
"I quickly hid my cell phone in my pajamas. I pretended like I didn't know what they were saying and I kept speaking in Korean," she said.
The suspects duct taped her and left her alone to find her parents.
The victim tore through the tape, emailed a friend to call 911 and dialed 911 herself.
In the next room, authorities say, the suspects tied up the victim's parents.
"My dad kept telling them please don't hurt my daughter, she's my only one," she said.
The suspects returned and hit the victim over the head with a gun, after they realized she called police.
Minutes later, at the sound of sirens, the suspects fled, taking off with some cash.
The victim had to undergo a cat scan and doctors think she suffered a mild concussion.
Her quick thinking helped save the lives of her family.
"They keep saying that but I don't feel that way at all," she said.
Police believe the victim's father, who owns a business in Philadelphia, was a target.
Authorities say the suspects may have thought that he brought home a lot of cash.
"I think it's because of a stereotype that Asian people hold a lot of money at home and we don't," said the victim.
Police are investigating whether another break-in and an attempted break-in, which happened this year in the same neighborhood, are related.
Authorities are also looking to see if a November home invasion in Hatfield, involved four armed men, can also be linked.
