Trot queen Jang Yoon Jung explains why she became known as "Cash Yoon Jung" ("Yoon Jung and Cash").

On last night's episode of SBS' "Healing Camp", Jang revealed that she pays her husband Do Kyung Wan's credit card bills. She went on to say that he didn't marry her because she "earned a lot of money, but because I became known for spending and treating others." 

She also pointed out that her younger husband's career experience is also 10 years shorter than hers.

"I pay for drinks and when he needs living expenses, I become 'Cash Yoon Jung'," she candidly explained.

Jang and Do married in 2013. Before marrying, Do was known for being Jang's biggest fan.

During an episode of a new trot entertainment program "Heir" this past July, Do revealed that his favorite song of his wife's was "First Love." He stated that his favorite lyric from the song,"Hold my hand and accept my love," inspired him to pursue and fall in love with Jang. 

While she handles her husband's finances, she also mentioned that frequently shows him how much he's earned to remind him of his earning potential, and how thankful she is for that. This is because she hasn't "supported anyone financially yet," and she is grateful that her husband's financial stability.
