Are Yang Jian and Nezha in The Journey to the West the same person as Yang Jian and Nezha in The List of Gods?

Many ancient myths and legends in China have a certain origin, or you can go back to a certain era and look for their original images.

For example, Yang Jian, as you said, gradually became a god in the Romance of Gods. In Jiro Bao Juan, he chopped a mountain to save his mother. In the The Journey to the West, he captured the Monkey King alive. In Lotus Lantern, he hinders Sean from saving his mother. In fact, they are all immortals.

Many authors can't help but use their own characters when creating characters, mainly for the service of this book. In the Romance of Gods, he followed Jiang Ziya and played a positive role. In Lotus Lantern, he is the villain. This is decided by the author, not by the gods themselves. After all, people write books and have their own preferences. No matter which fairy they like, they will transform their personality, appearance and so on.

Nezha, too, as a fairy with high popularity, was deeply loved by the broad masses of the people and basically played a positive role. However, some net writers also bring you some different feelings.

In fact, the list of gods and the journey to the west are related, so it is normal to have the same god.
