The reason it's called Han Mo is because Wang Taika has been on business trips all the time, and even forgot his name. He only remembers that the letters are py, so just call him Hanpy.,As a documentary filmmaker, Wang Taika's physical fitness could reach the level of a survival expert. Otherwise, it would be impossible for him to have visited so many dangerous places and survived safely. So, he knows or has heard of almost all the well-known survival experts in China.,“Hello everyone! I’m Gongsun Hu, a survival expert. You can call me Tiger Brother!” the burly man said to the camera in a dramatic tone: “I have a strict temper and won't relax my requirements because you are celebrities. Because that would be irresponsible to your lives! This is deep in the mountains, a very dangerous primeval jungle. There might be some crises inside, so for your own safety, you must listen!”。
