Twenty-four-year-old Dai Haifei lived in an egg for two months in Beijing.He is among millions of youth who have come from all parts of China to the mega city to pursue their dreams, but find difficulty coping with the high living cost. So, he decided to build a home by himself, an egg-shaped home that costs little to live in.rnI want to have a home of my own, no need to be too big, as long as it shelters me from the sun and the rain, he said on his blog explaining the egg house. I do not want to live in a remote cer of the city."
