So Wong specially brought in a cheese expert from his alma mater, the University of Wisconsin, who spent three years finding a method to take the odor out and creating a cheese with a unique flavor. Wong taught the method to the nomads, greatly increasing the value of yaks.
為此，黃效文特地從母校威斯康辛大學請來乳酪專家，花費 3 年時間把犛牛奶去腥，調製成風味獨具的乳酪，並向牧民傳授技術，大大提高了犛牛的價值。
