How did Gemini come from?

Zeus, who was infatuated with the beauty of Spartan princess Leda, turned into a swan to approach her, and they gave birth to twins-the son of borax and the son of man, Caster. Both of them are brave and adventurous warriors, and they often make great achievements together. They also have a pair of twin cousins-Iddas and Lincks. One day, four people are going to catch cows. When they caught a lot of cows and prepared to share them equally, greedy Iddas and Lincks took advantage of borax and Caster's surprise and snatched them back. The enraged twins had a big fight, and Iddas shot casto with an arrow. Borax is very sad. He wants to go to heaven with Kaster, but he can't because he has eternal life. His grief touched Zeus, so he set up a constellation for them, living in the kingdom of heaven and the country of death respectively. Gemini's younger brother, Beta Star, was called "North River III" in ancient China, but it is brighter than its older brother, Alpha Star, and is the 17th brightest star in the whole day. Brother Alpha, known as "Beihe II" in ancient China, is the first confirmed binary star in the history of astronomy. In fact, it is a "six-star" composed of six stars. Interestingly, my brother Beichuan is also a Liuhe star. Gemini has a meteor shower, called Gemini meteor shower. Its radiation point is near Alpha Star, which appears around11every year, and the meteor reaches its peak at 13.
