The truth about Kang Ho-dong's spring greens bibimbap.. The legendary Kang Ho-dong's spring greens bibimbap was filmed by PD Na Young-seok and PD Lee Myung-han. The only people on Earth who have tasted it are Kang Ho-dong, Na Young-seok, and Lee Myung-han. They thought it was spring greens, but no matter how they made it, they said it didn't taste the same. But it turns out it wasn't spring greens, it was young napa cabbage. We've all been fooled, everyone.
