MBC entertainment program 'Infinite Challenge' members Haha and Jung Hyung Don abandoned the original building the bridge project and worked as palanquin bearers in the deep mountains of China.

On the most recent episode of the popular MBC entertainment program 'Infinite Challenge,' which aired on June 5, 2015, the Infinite Challenge members Haha and Jung Hyung Don chose a new project which they had to walk up the stairs of the mountain carrying a tourist in a palanquin. They moved location and picked up the palanquin they would be holding for the customers. Haha bore it for a minute, and announced he is giving up. When the staff asked why, he said, dingily, "Because I am afraid my customer will get hurt," making people laugh. Later, Haha and Jung Hyung Don gave customers rides, including those who were Infinite Challenge fans, climbing up and down 1,200 stairs for just under 10 dollars. In related news, on the most recent Infinite Challenge project, the members were paired for different projects. The Haha and Jung Hyung Don team left for China. The Yoo Jae Suk and Hwang Kwang Hee team left for Mumbai, India. Lastly, the Park Myung Soo and Jung Joon Ha team went to Nairobi, Kenya. The MBC entertainment program 'Infinite Challenge' is one of the popular, long lasting entertainment programs in Korea. It features the Infinite Challenge members Ha Ha, Park Myung Soo, Yoo Jae Suk, Jung Joon Ha, and Jung Hyung Don.
