According to Hmong tradition, at the beginning of time, God sent each of his twelve sons to different places on the earth, bearing a message of salvation. When the saviour arrived amongst the Hmong people, however, the Hmong were afraid of him and killed him. God sent three subsequent messengers to the Hmong, but they killed them all, so God condemned them to endure punishment until the year 1957, when he would deliver them.
At the appointed time, one of God's sons was once again selected to go to the Hmong people. The first time he was sent, he did not complete his task and instead returned to Heaven. He was born again in 1929 as a Hmong boy by the name of Shong Lue. Unfortunately, by the time Shong Lue was nine, his parents and all his siblings had died and he was alone. He went to live in a neighbouring village, where he remained until he was an adult, marrying and having children. In 1959, Shong Lue had a vision from God, telling him that he had been sent to the Hmong people to deliver them, and that he was to prepare and smoke an opium pipe so that two of God's other sons could communicate with him. At this time, he was illiterate.
Some nights later, Shong Lue prepared and smoked the opium, and two men appeared in the room and began teaching him the Pahawh Hmong script. This happened for a number of nights. At this time, Shong Lue's wife became pregnant, and five months later gave birth to two twin boys. These boys were in fact the same sons of God who had been visiting Shong Lue in adult form.
The two boys died within a few weeks of being born, but not without leaving Shong Lue written instructions as to the propagation of the script. They instructed Shong Lue to teach the script to both the Hmong and the Khmu people, and that whichever group accepted the script would be blessed and would increase; the other would be cursed and remain downtrodden and poor.
When Shong Lue read the message, he remembered everything that had happened in his previous life in Heaven, and his first birth on the earth. He returned to the family into which he had first been born, and to the children he had borne the first time he had come to earth, and they corroborated his story.
He taught the Hmong and the Khmu people the script and gave them the message from God about how to live as good people on the earth. Reportedly, both groups accepted everything he said, although little documented use of the Pahawh Khmu script exists. The Hmong came in increasing numbers and Shong Lue gained widespread influence. The authorities, however, felt threatened by his power and by the love the Hmong people had for him. He was killed in 1971 on the pretext of CIA involvement.
