A recent reality TV, program called "Metamorphosis (Bian Xingji)" has stirred up debate. The program, which aired on Human Satellite TV, offers two primary school students a chance to exchange life roles. For one week, Gao Zhanxi, a poor country boy from Qinghai, and Wei Cheng, a rich city boy from Hunan, walked in each other’s shoes. Many people praised the program because it changed the kids in good ways. Wei has decided to throw away his former extravagant lifestyle and keep away from Internet games. Gao opened his eyes to see a wonderful world outside the mountains. But others don’t agree. They think the program actually hurt Gao a lot. He actually wept when he first tasted modern life. People doubt whether he will turn to his poor family willingly without feeling the inequality of life after experiencing the colorfulness of city life. Someone says,"Gao is just too young to experience the huge gap between his country life and the far-too-good modern city life. He may think that life hasn’t treated him fairly. He may even hate society’s inequality. The program hurts him, for sure.\ What does the phrase "walked in each other’s shoes" in the first paragraph mean ______.
A．To exchange shoes with each other. B．To be in each other’s situation. C．To make choices for each other. D．To feel quite uncomfortabl
