"Brother, you've been depressed for over a week now, and I can't stand to see it anymore." The person pulling the curtains was backlit, making their features somewhat unclear. But Wang Taika knew immediately who it was just from his soft, gentle voice. It was Han Mo, his roommate and good friend.,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!”。
