The Son of a Horse (Chinese folktale)
The Son of the Horse is a folktale from the Salar people, an ethnic minority in China. It concerns a hero of animal parentage and his adventures with two companions. Similar stories are located in China, among its ethnic minorities. The tale is related, in the international Aarne-Thompson-Uther Index, to type ATU 301, "The Three Stolen Princesses". Summary 
A family owns a black mare. One day, the owner finds the mare in labour in the stables. She foals a young boy. The owner takes the boy to the imam, who names him Ma Shengbao ("Baby Born of a Horse"). The owner adopts him as his own son, and he learns kung fu and archery. Years later, Ma Shengbao decides to leave home to find himself some brothers. In his wanderings, he sees smoke coming off a tree and shoots an arrow at it. A man comes out of the tree and says that Ma Shengbao broke his pot, but both become sworn brothers. Next, the duo walks on until they see smoke coming out of a rock. Ma Shengbao shoots an arrow at it. A man comes out of the rock and says Ma Shengbao broke his cooking pot. They decide to become sworn brothers. Now a trio, the man from the tree is called Big Brother, the man from the stone becomes Second Brother, and Ma Shengbao is called Little Brother (by degree of seniority). They live and hunt together. One time, when they return home, they find a meal prepared for them. They decide to be on the lookout in turns to discover who made it. Big Brother finds out that three doves fly in, become human maidens, prepare the food for the men, and fly back. Big Brother does not report the fact to his companions. The same happens to Second Brother. Ma Shengbao, Little Brother, spies on the dove maidens, takes their feathers and burns them to have them become humans permanently. The dove maidens introduce themselves as a trio of sisters, the first named Ayi Ana, the second Yulutusi Ana, and the third Guni Ana. Guni Ana is the most beautiful of the three, but she smears her face with soot to hide her beauty. Ma Shengbao's companions decide to marry the maidens, while he gets to stay with Guni Ana. Some time later, the maidens are cooking food at home, when a chicken comes out of nowhere, flutters its wings and snuffs out the fire in the hearth. The maidens leave home to look for another source of fire, and see smoke coming out of a cave. They enter the cave and a demoness, disguised as an old woman, gives them a piece of hot coal and a pouch of fruit. The maidens go back home; their fruit pouch rips open and pieces fall one after the other, creating a trail for the demoness to follow. The old woman tricks the maidens into allowing them to delouse their hair, but in fact she begins to suck their blood. Ma Shengbao and his companions notice that their wives are looking weak, emaciated and pale for the past days, and decide to investigate. Big Brother stays on the lookout and sees the demoness sucking the maidens' blood, but reports nothing to his companions. The same happens to Second Brother. Ma Shengbao discovers the truth and injures the demoness with his bow and arrow. Hurt, the demoness kidnaps Guni Ana and flees, leaving a trail of blood. Ma Shengbao follows the trail to a cave and asks his companions to rope him into the hole. Down there, he finds his wife, Guni Ana, who tells him to hide, since the demoness will come back soon. Ma Shengbao and Guni Ana kill the demoness, and he takes his wife to the rope, along with the devil's treasure. Ma Shengbao's companions lift the maiden and the treasure, but leave him stranded underground. Ma Shengbao wanders off underground, but falls exhausted and sleeps. When he wakes up, a snake threatens a young eagle, but the youth saves the bird by killing the snake. In gratitude, the young eagle carries him to its eagle parents atop a tree. The eagle mother agrees to lift him back home, but it must be fed a hundred sparrows for it to complete the journey. Ma Shengbao manages to capture 99 sparrows, and begins the journey on the eagle's back. After exhausting the sparrows, Ma Shengbao cuts off part of his leg to feed the eagle near the end of the journey. After they land, the eagle notices that the youth is limping, and scolds him. Ma Shengbao hobbles back home and stops to rest by a well, when he sees a woman coming to fetch water. The woman, Guni Ana, recognizes the man as her husband, and explains his companions are mistreating her. Ma Shengbao comes home disguised as a tattered man, and finds his two companions practicing martial arts in the garden. Ma Shengbao challenges and beats them. Defeated, Big Brother and Second Brother flee with their wives, leaving Ma Shengbao and Guni Ana. The pair lives happily. Analysis

Tale type 
The tale is related, in the international Aarne-Thompson-Uther Index, to tale type ATU 301, "The Three Stolen Princesses" and its subtypes: a hero - often having an animal parentage - finds two companions, climbs down a hole and rescues three maidens from their underground captivity; he is betrayed by his companions and trapped underground, but eventually finds a way out back to the surface - usually by flying on an eagle's back. According to Chinese folklorist and scholar , tale type 301 in China forms its own cycle of variants, including those from the ethnic minorities of China. Motifs 
The women that become birds and vice-versa represent the international motif of the swan maiden: females that alternate between avian and human shapes by the use of a feather cloak or garment. However, Ting Nai-tung supposed that this motif was "unknown to other Chinese versions of AT 301". The episode of the journey on the eagle's back is parallel to similar events in many fairy tales, where a hero needs to feed pieces of meat to the eagle (or another mythical bird) for the remainder of the journey, otherwise it will not complete its flight. In this regard, folklorist scholarship recognizes its similarities with the tale of Etana helping an eagle, a tale type later classified as Aarne–Thompson–Uther ATU 537, "The Eagle as helper: hero carried on the wings of a helpful eagle".

Russian philologist Aleksandr Gryunberg-Tsvetinovich and philologist  collected a tale from an informant that lived in Wakhan, with the title "Май-Зман" ("Mai-Zman"). In this tale, an old woman lives with her grandson and a sheep that gives birth every day to a lamb. Every day, its lambs are eaten by the boy and her grandmother. One day, the boy announces that he plans to eat the sheep, a decision agreed on by his grandmother. So, they lock the animal in a pen. A cat goes to talk to the sheep and reveals the humans plan to eat it bit by bit, and the cat wishes to eat the sheep's tail by stealing from the old woman's house. To save its life, the sheep offers to cut off its own tail for the cat, in exchange for its release. The cat brings a knife, the sheep cuts off the tail and flees to Mount Kof. There, safe at least, the sheep gives birth to a flock of lambs and eventually to a human boy. The boy, named Mai-Zman ("Son of the Sheep") grows up, and is ordered by his mother to live with humans. Before he leaves, the sheep-mother gives some hairs from its head for her son to call on her aid. In his wanderings, he meets three equally strong men: the first named Chinorboz ("Playing with trees"), Kuboz ("Playing with mountains") and Hdorgboz ("Playing with millstones"). Mai-Zman wrestles against each one and, defeating them, they become his sworn brothers and companions. Now a quartet, the four heroes find a deserted house and live there, and take turns hunting game for them and cooking their food. As time goes by, they notice that someone enters the house, prepares the food, grooms their hair and beards, then leaves. Mai-Zman's companions decide to be on the lookout, but find nothing. Mai-Zman stays awake and discovers a girl. He talks to his companions and they all agree he should have her as wife. Later, Mai-Zman warns his wife not to let the fire in their hearth to go out. However, it does happen and the girl needs to look for another source with a distant neighbour, an old woman named Barzangi. The old woman tricks the girl into removing lice from her hair and gives her a coal, then goes to her house and drinks the girl's blood. Mai-Zman notices his wife is becoming weaker and decides to investigate further: after his three companions fail to notice any strange presence, Mai-Zman discovers the Barzangi, which becomes a multi-headed monster. They engage in fierce and bloody combat, Mai-Zman cutting off Barzangi's heads until leaving only one. Mai-Zman's wife takes off the sheep's hair from her husband's belt and summons the sheep to restore the heroes, who follow the creature's blood trail to a hole that leads underground. His companions failing to go down the hole, Mai-Zman climbs down himself with a rope and meets a shepherd in the lower world that works for a pair of old people. The shepherd reveals that the lives of the three of them are hidden each in a louse. Mai-Zman smashes the louses, kills the shepherd and the old couple, then takes the shepherd's cattle to the rope. His companions pull the cattle out of the hole and leave the youth trapped underground. He then meets a Simurgh bird and takes out from its leg a thorn that became a forest. In gratitude, the Simurgh agrees to take Mai-Zman back to the surface. See also
