Woo Hyerim a former member of Wonder Girls, shared the background of her exclusion from activities in China in the past.

Woo Hyerim appeared as a special MC on KBS-2TV's 'New Family Relations Certificate, Godfather' (hereafter referred to as Godfather), which was broadcast on the 28th.

Broadcaster Lee Geum-hee mentioned Kim Sook and Jonathan's diet on that day, and then asked Woo Hyerim about weight loss after giving birth.

Woo Hyerim said, "I still have 5 kg left to lose weight. The thing I'm most worried about is belly fat."

Afterwards, episodes of Kim Sook and Jonathan who went on a camping diet appeared on VCR. Jonathan ate late night snacks such as ramen and sweets without Kim Sook's knowledge, causing laughter.

Seeing this, Woo Hyerim deeply sympathized with it. She looked at Jonathan and said, "(Ramen) is the best to eat at that time."

She also once confessed to the difficulties of dieting as a member of 'Wonder Girls' and the failure of her activities in China due to this.

Woo Hyerim said, "I had to do group activities in China, but I couldn't lose weight, so there was a time when a team went to work except me."

At this, rapper Grie couldn't hide his surprise, saying, "Wow, loosing weight was really important at that time I guess."

'Oh My Girl' Seung hee, an active girl group member, said, "Stress is so bad (for diet)." "In my case, I turned off the lights in the practice room and played exciting music and danced. Once I do that I lose weight and relieve stress." She shared her secret with the group.
