Chu Hai-jun, who was selected by the Guiness Book of World Records as the shortest woman in the world, is getting an operation that will extend her height. Chu's height is 79cm, which is shorter than the lower half of an average woman's body, and her weight is 10kg. A Chinese news reported that she is in hospital under the care of her grandmother. Her grandmother has taken care of Chu for 20 years since Chu's parents refused to bring her up. She said, "Chu's mental age is only 2. I spent 60 thousand yuans over the last several years to get her receive medical care, but it was useless. Chu was not born short. Her growing rate has become slow since she fell into a disease when she was a baby." Dr.Chai Huing who will perform the operation for free said, "Chu is suffering from hypophyses underdevelopment."
