Gu Ran learned batik skills from his grandmother, who always said, "The batik patterns contain the words of our ancestors, and only certain people can understand them." Until my grandmother passed away, when she was sorting out the batik cloth, she found a piece of cloth painted with strange patterns. The outlines of "Flood" and "Village" could be vaguely seen in the pattern, and the edges of the cloth were embroidered with the same pattern as her scarf.
The old batik artist in the village told her: "This piece of cloth is an 'early warning cloth'. The pattern indicates that the village will face floods. Your grandmother relied on it to move the villagers in advance." Gu Ran followed the pattern and found her grandmother's batik diary in the cave behind the village. The last page showed the design of a dam to deal with floods. That night, Gu Ran used batik techniques to reproduce the design drawings. The villagers built the embankment according to the drawings, and the flood pattern on the "warning cloth" slowly turned into a calm river.
