Jang Yun-jeong revealed the anecdote of Ha-yeong Lee, In the 34th MBC performance 'the water-crossed Fathers' broadcasted on June 4, the wise Twins child care law of Canadian Father Denny's, who is currently serving as the vice principal of Gyeonggi International School, was revealed. On this day, Denny's asked Twins daughter Brook to write a praise record on the white board when she had a concert with her brother Grace. Kim Na-young said, "Yes, I forgot, and I insisted that I had a session last time." In the studio, there is a lot of 'concession to my brother' mind in Korea. "A consultation is typically something that should be praised when you do well," said no gyu-sik Doctorate, a specialist in general health medicine at a parenting mentor. "If you don't do a consultation, you shouldn't say, 'Why do you do it because you're older and you're older,' but when you do a consultation, you should say, 'Thank you for the difficult behavior.'" In addition, no gyu-sik Doctorate advised Minori, a Japanese Father who is worried about his son who is not good at a concession because he is an only child, to take him to volunteer activities and teach him to give. Among Denny's parenting methods, the Twins daughter's refusal to intervene as a parent when fighting over one item was also well-received. According to the no gyu-sik Doctorate, this behavior has the advantage of making it instinctive to think that it is better to solve this problem and have a good time while at the same time focusing on things or events without thinking "Mom, Father likes him more". However, no gyu-sik Doctorate advised me to keep a distance as long as I can see that there may be cases where children fight. At this time, Kim Na-young asked, "My family did not intervene because they told me not to intervene, but a child who couldn't bear it kept getting hit. They lost money," and asked if he could leave it alone. no gyu-sik Doctorate said, "You just have to try to soothe your heart. It's better to just hug it so you do not get upset. If you try to balance it, it goes wrong from here." When I continue to be beaten by my brothers, I learn skills to win. I get better social skills than my peers. I get hard training unexpectedly. " Jang Yun-jeong guessed that in the second case, "Friends will fly in No Strings Attached." Jang Yun-jeong said, "When we see Ha-yeong and Ha-yeong fighting, Ha-yeong says, 'It's my brother!' I was worried he'd yell when he didn't get his way in Friends No Strings Attached. So when Ha-yeong was playing, he'd say, 'Hey!' 'Ha-yeong looked at him with a look that he was too stupid and said,' Mom, I'm not such a bad boy. '" Jang Yun-jeong added, "Knowing how to live among the children."
