While living in the United States, Chang discovered this stone, shaped like the island of Taiwan, and placed it in his garden in Los Angeles. Later, when he came to Taiwan, he had it shipped over especially for his garden. On the stone are carved the two characters "Plum Hill," executed by the master's own hand.
