During an interview with Star News on January 8, Jung Chae Yeon was asked about her nickname 'dachshund'. 

The idol star commented, "I wore pants during 'Drinking Alone' and proportionally, my legs looked short. It was upsetting. You measure the length of your arms and legs every time you have a new stylist. So I told my new head stylist that my leg measurements might be shorter than the other members because I really thought I had short legs but when we actually measured, it was about the same. So I was like 'Hmm..' But then I already had the nickname (for having short legs)."

She continued, "It was upsetting. So I thought about the cause (of why they look short) and I realized that a person's leg looks long if you have long calves but I tend to have long thighs. It's upsetting... So I'm trying pilates to make my body prettier."
