With a pair of ears, he can hear the safety of the dam, and with a handful of soil, he can tell the distance of the flood peak. Amidst the decadent bureaucracy and lack of money, he guarded the embankment with his flesh and blood, turning every stormy wave into a page of experience. This is an epic of river management by a small official, witnessing how the turbulent waves dig out real gold, and how a humble person becomes the unknown backbone of the dynasty.
