This is an attempt to create a topographical fable blending the humanities and ecological science. The work uses research hypotheses and hearsay evidence to express a biological fable about the coastal intertidal zone at Wuteh on Penghu. In the intertidal zone at Wuteh, the long-term thriving growth of salt-tolerant plants and shellfish, and residents' economic activities and everyday lives, are important biological production mechanisms for the intertidal zone's ecology.

The local women use shovels to dig up many kinds of mollusks in the intertidal zone when the weather is good. This type of laborious but low-income economic activity has long supplemented the local people's protein intake and met their minimum financial needs. The women's oral accounts of their lives and fates provide indispensable evidence of the community's way of life. The salt-tolerant plants see this and continue their growth through quiet change. And the mollusks that live in the briny sand and been coexisting with other species for ages continue their lives.
