Lu Zhihao, 4, takes a shower with the help of his mother at his house in Foshan, Guangdong province March 28, 2011. Lu, who is 1.1m tall and weighs 62 kg, put on weight dramatically since his appetite grew when he was 3 months old. His worried parents took him to several hospitals, but the reason for his obesity remains unknown, though it is possibly due to his dietary habit, according to local media.
