Jang Yoon-jung caught attention by sharing her honest reaction to MZ generation fashion. In the video titled "What Happens When Nayoung and Yujin Ask to Hang Out" recently released on the YouTube channel 'JangGongJangJangYoonJung,' Jang Yoon-jung met with her juniors Nayoung and Jeon Yu Jin in Hongdae.

During a phone call with Nayoung, Jang Yoon-jung said, "There's an age gap of several years, why should I hang out with you? Are there people my age in Hongdae?" When Nayoung replied, "There are people of all ages," Jang Yoon-jung gave a wry smile at the word 'old.' Even after setting the appointment, she added, "There's a 25-year age difference, that's amazing. Young people these days are really surprising. I don't know why they want to hang out with me," and "I'm an ajumma and I have kids."

The three met at Sangsu Station and visited a vintage shop in Hongdae. Seeing the MZ style of her two juniors, Jang Yoon-jung said, "Can I be honest? You guys look like beggars, like double beggars," which made everyone burst into laughter. At the vintage shop, after being recommended layered style outfits, Jang Yoon-jung expressed reluctance, saying, "Isn't this a tablecloth? I think I'm going to get mad. I really can't wear this," but she tried on the clothes at her juniors' urging. While saying, "Why did I meet these rascals? Why do kids these days wear such baby-like clothes?" she still pulled off the styling. She showcased a fashion of a printed white T-shirt layered with a light green long skirt and jeans, and even paid for her juniors' clothes herself.

Jang Yoon-jung married announcer Do Kyung-wan in 2013 and has one son and one daughter. In 2024, it was revealed that she purchased a penthouse worth around 12 billion won entirely in cash.
