In the original work, cows used mixed iron bars. On the Journey to the West, they returned 60 blows to the cows and went to China for dinner.

The good devil dragged it away, went out of the study, took his coat in the hall, and took a mixed iron bar. When he went out, he shouted, "Who's coming with me?"

In the 86 edition of Journey to the West, the mixed iron bar was replaced by the mace, because the mace can better reflect the momentum of Niu Wangmo.

As for the sword, when Niu went to the Dragon Palace for dinner, he found that the beast with clear water and golden eyes was stolen, forgot to bring his weapon and asked Princess Tiefan to borrow it.
