Who is the owner of Chang 'e?

According to Wikipedia, the owner of Chang 'e is the moon star Wang, also known as the moon god in ancient times. Lunar Xing Jun is a noble and beautiful fairy who is in charge of the changes of the moon and the fertility. She once took Chang 'e as an apprentice, taught her to cultivate immortality and gave her elixir of life. Later, Chang 'e rose to the Moon Palace because of taking the elixir of life, and became a fairy in the Moon Palace. As for why Pig Bajie was thrown into the mortal world as soon as he met Chang 'e, this is a story about Journey to the West. The Journey to the West is a famous classical novel, which tells the adventures of the Monkey King, Zhu Bajie, Friar Sand and Tang Priest. In the nineteenth episode, Pig Bajie secretly went to the Moon Palace to flirt with Chang 'e because of his lust for Chang 'e's beauty. The jade emperor found out and ordered him to be reincarnated.
