Legend has it that a person, a woman, appeared three years ago. Originally, the appearance of a woman was nothing, after all, there were so many women in the world. But there is something special about this woman. It's not that she has three heads and six arms, it's just that she carries a dagger called Hanjiang Dagger.
Hanjiang is another name for tofu. There is a description in the "Huainan Wang Pian" from the Han Dynasty Yuefu Songs: "A well was dug in the back garden to make a bed, and a gold vase was made of plain silk to collect cold slurry." "Han slurry" is tofu.
The name of the dagger Hanjiang Dagger does not mean that it is like tofu, but that everything it faces will become tofu.
Three years is enough time for a pearl to emerge from the sand, and enough time for a good weapon to become famous.
