Jianghe Town is located in the folds of the remaining veins of Changbai Mountain. The blue-gray stone Zhenhai Monument at the east end of the town has been there since the late Qing Dynasty. It has never been moved despite the wind and rain for many years. The elders gossiped that there was an "aggrieved dragon" buried under the monument. During the Republic of China, the monument had a small crack on its body. That year, seven families died in the town, and the cries could be heard ten miles away. During the famine in 1962, red water seeped through the cracks. After the first spring rain in 2025, half-year-old children from the middle school in the town ran like crazy to report that the cracks on the monument had widened again, and the mucus oozing out was as sticky as fat, and would condense into a fish-scale hard shell after being exposed to the sun. The old neighbors trembled as they looked at it, slapping their thighs and shouting: "This is 'evil ambergris'! If the monument cannot be suppressed, our town will have to finish it!"
