每人都各有所長，故訓練人才必須把所有鐵鏽打掉，丟入熔爐，千錘百煉，才能成鋼。
Everyone has their own strengths. Therefore, the training for talents is like that of a blacksmith, starting with striking off the rust on the iron, then throw the iron into the furnace, and repeat the process of striking the iron while hot and heating again until the steel is made.
