Yang Jang Mo was part of a show called "Star Audition: The Great Birth" and was mentee of Kim Tae Won. And Park Chorong was his student. 

From the recent interview with a reporter, he said, "Years before I auditioned for "The Great Birth", I worked as vocal trainer at Choongbook Chungju. I almost taught every kids there were in Chungju. And one of them was Cho Rong." And then he said, "I trained her for 2 to 3 months. And when she became a trainee. we sometimes messaged each other. But I did not knew she would debut this fast."

And, when Yang Jang Mo said about Cho Rong when she was senior in high school, "She did not changed a thing. She was different from other kids when it comes about singing. I thought she would become someone special." "Back then, she sang well and really tried her best." He also explained, "When I thought she was same A Pink Cho Rong as before, I was proud of her and felt great because she was one of my student."

Afterward, Park Cho Rong said she remembered her teacher, Yang Jang Mo. According to her company, she said whenever "The Great Birth" aired, she cheered for him.
