'Miss Trot 2' Baby Tiger Kim Taeyeon's recent news was revealed in 'Donkey Ears'. On KBS2 Boss in the Mirror' broadcast on the 4th, debut 50th year stage president Yonja Kim joined the new Bose Corporation. Jang Youngran, who appeared as a special MC on the day, praised Yonja Kim, saying, "I used to be a judge on the trot broadcast, but at that time, I felt like I was too open and open. Then Jeon said, "If you don't look angry, it might not be a joke behind your back. I'm worried about that." Yonja Kim said, "You won't press the 'A' button. It's the same behind your back." Yonja Kim, who has been a singer for 50 years, said, "Can I praise myself? I am kind to everyone. I think I am a kind person." However, Hwang Min-woo said, "It's a scary Bose Corporation. I learned a song from Yonja Kim, but I was angry for three or four hours." Yonja Kim's sharp points such as "I am comfortable and I am just as good as I am", "I should not be wrong", "Have you come to the funeral?" Taejoo Na explained, "I have to make my teacher feel good in a good place in commemoration of Teacher's Day." Then, the panels that saw the girl caught on the screen said, "Taeyeon?" And "Taeyeon?" Three years ago, when she appeared in 'Miss Trot 2' as an elementary school student, it was hard to match her with the same person in a recent situation that she could not find. When Kim Taeyeon, who appeared on the interview screen, introduced himself, the panels were shocked, saying, "Why was Taeyeon so big?" Jang Youngran was surprised that "Litter was missing," and Kim Hee-chul admired it as "it was really big." Among them, Taejoo Na explained, "I was in this position to have a small party and a good time for Yonja Kim in commemoration of Teacher's Day." KBS2
