Is Erlang Shen (Yang Jian) Hou Yi?

That's not true. The two ages are different. In ancient times, Hou Yi was a man, not a god. It was the period of Huangdi, Fuxi, Kuafu, Chiyou and Shennong. A stone age god belonging to the Han nationality. At that time, people believed in different things. At that time, the envelope was written about nature, strength, medicine, spirit and heroes who defeated nature. So Hou Yi didn't become a god at all, just a hero. After all, Erlang God was born in the apotheosis era. The days have changed, and Erlang God is the second child of the jade emperor's sister Yao Ji. Nephew of the Jade Emperor. In the TV series, Chang 'e said that Hou Yi also thought it was Hou Yi, maybe he looked like him, maybe he looked like him. Don't turn that TV play into a fairy tale just because you are too lazy to watch it. Lotus lantern is just to make the plot rich and colorful, and it has given Erlang God Houyi the opportunity to shoot the sun, split the mountain to save his mother, seal the gods list and travel to the West. Besides, when Erlang shot the sun, he dared not say it was Hou Yi. At most, it is to copy the Houyi shooting day. Don't be misled by TV plays. There is no prequel to Lotus Lantern in the original work. It was written by a screenwriter. But it's quite compact. Just for fun. No myths. It will make people laugh.
