Chang, who has treated innumerable patients, talks about his development as a surgeon: "Using traditional methods, I discovered that there were many problems that frequently came up-the corrective results were less than ideal, the procedures were too complex and took too long, there was too much risk, and so on-and over my career I have always been thinking about to how innovate and improve."
病患不計其數的張國華說，「過去使用傳統手法，發現老是出現一些共同問題，如矯正效果不佳、手術太複雜、時間太長、危險性高等，就一直想突破創新。」
