In A.D. 712, in the reign-period K'ai-yüan of the Emperor Hsüan Tsung of the T'ang dynasty, they both returned to the Tung-t'ing Lake; but the legend says nothing further with regard to them.
Shang Ti, the Supreme Ruler, conferred on Liu I the title of Chin Lung Ta Wang, 'Golden Dragon Great Prince.'
The Old Mother of the Waters, Shul-mu Niang-niang, is the legendary spirit of Ssu-chou, in Anhui. To her is popularly ascribed the destruction of the ancient city of Ssu-chou, which was completely submerged by the waters of the Hung-tsê Lake in A.D. 1574.
One author states that this Goddess of the Waters is the younger sister of the White Spiritual Elephant, a guardian of the Door of Buddha. This elephant is the "subtle principle of metamorphosed water."
In his _Recherches sur Us Superstitions en Chine_, Père Henri Doré, S.J., relates the legends he had heard with regard to this deity. One of these is as follows:
Shui-mu Niang-niang inundated the town of Ssu-chou almost every year. A report was presented to Yu Huang, Lord of the Skies, begging him to put an end to the scourge which devastated the country and cost so many lives. The Lord of the Skies commanded the Great Kings of the Skies and their generals to raise troops and take the field in order to capture this goddess and deprive her of the power of doing further mischief. But her tricks triumphed over force, and the city continued to be periodically devastated by inundations.
One day Shui-mu Niang-niang was seen near the city gate carrying two buckets of water. Li Lao-chün suspected some plot, but, an open attack being too risky, he preferred to adopt a ruse. He went and bought a donkey, led it to the buckets of water, and let it drink their contents. Unfortunately the animal could not drink all the water, so that a little remained at the bottom of the buckets. Now these magical buckets contained the sources of the five great lakes, which held enough water to inundate the whole of China. Shui-mu Niang-niang with her foot overturned one of the buckets, and the water that had remained in it was enough to cause a formidable flood, which submerged the unfortunate town, and buried it for ever under the immense sheet of water called the Lake of Hung-tsê.
