There's something really interesting happening with the silk imagery throughout this passage. Jiang He is literally handling bolts of silk — superior, medium, lower grade — and trying to understand the system that determines their value. The Bureau clerk tells her that even woven cloth can be traced back to the quality of the silkworm cocoons. You can't fool the professionals. This feels like a metaphor for the whole story. Jiang He's trying to rebuild her family's legacy, but the raw materials — the foundation — might not be what she thinks. The cocoons were lower grade, and no amount of skilled weaving can hide that. Meanwhile, Xie Zhao is someone whose past has been stripped away (amnesia), and he's trying to figure out what kind of person he was based on the residual skills he still has — horse riding, combat instincts, the way he rolls to absorb impact. He's like a bolt of cloth that someone else wove, and now he has to figure out what the original silk was made of. The oath scene is another layer of this. A sworn oath in Chinese literature is never just a promise — it's a binding contract with cosmic weight. But the author subverts it. Instead of a life-or-death oath, it's about commercial success. "May you never become a wealthy merchant." It's almost absurd, but it's also deeply meaningful. These two are binding themselves to each other through a promise about business, which is the one thing they both care about. Their relationship is being forged through commerce, through shared ambition, through the practical realities of making a living. The theme here seems to be: what we inherit shapes us, but how we weave that inheritance determines its value. And neither Jiang He nor Xie Zhao knows yet what kind of silk they're working with.
