Take the case of a severely humpbacked patient from Indonesia whom Chang treated. The patient's head was at nearly a 90-degree angle, almost touching the breastbone. The patient could not open his mouth, and had not eaten solid food in three months.
例如他曾治療一位來自印尼的嚴重駝背畸型病人，病人的頭骨已經快以 90 度垂直頂到胸骨，嘴巴根本張不開，3 個月無法進食，只能喝些流質食物。
