In Lotus Lantern, Jiro's mother is Yao Ji and the jade emperor's sister, so the jade emperor is actually Jiro's uncle. At that time, Yao Ji strayed into the mortal world in order to catch a monster. It was at this time that she met a scholar, Yang Tianyou. Because Yao Ji was outstanding and Yang Tianyou was good-looking, plus Yao Ji had never seen another man, so the last two men looked at each other and got married and had children on the mortal world.
At that time, Yao Ji gave birth to three children on earth, which can be said to have been stolen for more than ten years. The second of these three children is Yang Jian, the later Erlang God, the third is Yang Chan, and three virgins. Then their eldest brother is Yang Jiao, the eldest son of Yao Ji. This happy day didn't last long. Later, Yao Ji's affair with mortals was known to the Empress Dowager, and she told the Jade Emperor. It also made the jade emperor fly into a rage. After all, she was beaten in the face by her own sister, and the Jade Emperor was naturally more angry, so he sent many heavenly soldiers to let them take Yao Ji back.
Because Yang Jiao was Yao Ji's first son, he also inherited his mother's magic. He is a natural divine power, but also very simple and honest, especially filial to his parents. So, on the day when the mountain club surrounded the Yang family, Yao Ji and his father saw that he was injured, and they also fought back. However, the mountain will no longer have the ability, but also a soldier in the sky. How do two mortals fight? So in the end, Yang Tianyou and Yang Jiao's father and son also died at the hands of the heavenly generals.
