Since the front ends of both soles, along with parts of his heels, had died from frostbite, Gau would have to lose large portions of his feet, leaving him with reduced support when walking. Because of this, the doctors grafted pieces of flesh from each arm to each foot, creating new soles for him.
由於雙腳腳掌前段和腳後跟都已凍傷壞死，如果切除腳掌前段，將來走路會缺少支撐，很不方便，因此醫生從他兩臂臂膀取了一塊肉接在腳掌前，當作新的腳掌。
