I can see why da ji hates Jiang Ziya so much.

Da ji is a thousand-year-old fox. She has a younger sister who is a jade pipa essence. Pipa Jing went down to Chao Ge to see da ji. On the way, she saw Jiang Taigong open a divination hall. She was curious and asked Jiang Ziya to do divination. I didn't expect Jiang Ziya's critical eyes to see that Pipa Jing was a monster, so he picked up an inkstone and knocked it out on the ground, which subsequently triggered a lawsuit.

From then on, da ji and Jiang Ziya became enemies. Jiang Ziya couldn't sing in Chao Ge, so he went fishing by the Weihe River in Xiqiao.
