The Jade Emperor is a very prominent figure in Chinese Mythology. It is said that he was born as the crown prince of "the kingdom of Pure Felicity and Majestic Heavenly Lights and Ornaments." He essentially radiated light when he was born. During his early years, he was a very kind and charitable child. He would spend his time helping the sick and the poor, among other afflicted people. Even after his father passed away, he still continued to look after the needs of his people and made sure they were able to find peace and contentment.
The Jade Emperor had to pass through several kalpas before he could actually become the Jade Emperor. It is said that he passed through 1,550 kalpas, or periods of time lasting 129,600 years each, in order to cultivate Tao, or a particular view of the world. Upon completing this and another hundred million years, he became the Jade Emperor. All-in-all, the period of time it took for him to become the Jade Emperor is 200,880,000 years.
