According to Henri Dorés "Researches into Chinese Superstitions", in her 'human' form she carries a sword along with two buckets and has black hair with a youthful appearance.
Li Laojun (a famous philosopher from Dao that takes on a mythological personification here) suspected that she was going to attack Sizhou so while she was away, he led a donkey to the buckets and allowed it to drink the water.
Shuimu saw through Li Lao's scheme and overturned one of the buckets with her foot creating a massive flood which submerged the city.
The Monkey King tried to capture her but she continued to slip through his fingers and so asked Guanyin (the Goddess of Mercy and also the Bodhisattva Avalokiteshvara)[7] for help.
Shuimu was famished after being constantly chased so she went to a vermicelli stand where Guanyin (disguised as a woman) was waiting for customers with two bowls of food.
[3] In another tale (documented by Henri Doré) Shuimu fought alongside Tuhuogui (a fiery demon) against Wang Lingquan (The supreme God of Taoists) and his army (the celestial warriors) at the request of the Water Elephant.
The Red Child demon heated her water to the boiling point and so she along with her troops fled to a place called Sizhou, after which Wang and his army won the battle.
However, her mother-in-law found out about the whip and tried to do the same thing herself, only this time, the water did not stop flowing and the area became the spring Nanlao Quan (难老泉), a source of the Jin River (晋河).
