While sculpting, each cut requires that he hold his breath for more than a minute, and his grip must be totally steady. If you don't take the greatest of care, extremely small carving materials, such as sesame seeds and grains of sand, will break or fall to the ground and be forever lost.
創作時，每筆刻劃間需閉氣一分鐘以上，還要控制全身每條肌肉靜止不動，手指要穩定不能顫抖；雕刻極小素材如芝麻、細沙，稍一不慎，不是碎掉，就是掉落地面了無痕跡。
