A heavy rainstorm caused cracks to appear in the embankment under construction. Liu Yang risked his life and dived into the water to explore the location of the cracks. Dandan directed the craftsmen on the shore to prepare emergency supplies, and finally successfully repaired the embankment.
Liu Yang drew the "Design Drawing of the Anhuai Reservoir", with detailed notes on the dam structure, spillway location, etc. Wu Yue presented the drawing to the court. Emperor Jiajing praised him for his "exquisite thinking and sharing of worries for the country" and gave Liu Yang the official position of "Craftsman of the Maintenance Office of the Ministry of Industry."
