Why did Bigan die in the list of gods because the vegetable seller fell off his horse?

The story of Gamby and Unintentional Dishes is quite interesting. There are two versions of Beagan's story. One is that Jiang Ziya cut out his heart and asked him to go out of the city, to find an old woman selling water spinach and ask her if the dish was unintentional, could she live? If the old woman answers that she can live, she can live. If the old woman answers no, she will die.

Another version is that before his death, Bigan was told that Jiang Ziya gave Bigan a symbol, put it on his chest, and then rode out of the city and left the capital for two thousand miles. But on the way, he must not turn back. As long as he doesn't turn back, he can survive. When Bigan passed by the old woman selling water spinach, she heard the old woman selling water spinach selling unintentional vegetables. Bigan was curious and forgot what Jiang Ziya said. As a result, he turned his head, fell off his horse and died.

These two versions tell similar stories. In the first edition, some people thought so. The penholder was originally protected by magic, and even without a heart, it can still survive. However, when I met an old woman with water spinach, my heart was shaken by the old woman's question and I thought I would go to come to a bad end. He died after his willpower disappeared.

Therefore, some people think that Bigan's death has nothing to do with the words of the old woman who sells spinach, but with his own weak will.
