More about him: Jung Yunho (정윤호), secured his spot in TVXQ through a dance competition. He was the second member to join TVXQ. Prior to this, he accumulated some musical experience as a rapper and backup dancer for K-pop singer Dana in her Diamond video. His chosen stage name is U-know YunHo, because when you say YunHo really fast it sounds like "You know" in English. He is the second oldest member in TVXQ and is also the band's leader.

He began to dance in 7th grade where he made a dance team at his school and took them to a competition. During the depression, Jung YunHo's family's business was not doing very well and so he moved away from home and took many small jobs to support his sister's education. At the time he was in 9th grade and due to this, he often slept under the bridge of a train station. In extreme circumstances, he even begged for money. At this time he auditioned for SM Entertainment and was accepted.
