Embroidery Marks as Evidence

I am the most disliked lowly embroiderer in the Dajing County government office, my name is Shen Aying. While others investigate cases and perform autopsies to look for clues, I can restore the posture of the deceased when he was assassinated by patching up a broken stitch on a blood-stained coat; by comparing the twist direction of the embroidery thread on a handkerchief, I can uncover the connection between two murder cases hundreds of miles apart that were deliberately hidden. I was originally a modern technician of weaving traces, relying on every stitch and break of each silk thread on the fabric to restore the truth - after becoming an embroiderer, this craft became a unique "silk inspection" skill: broken burrs can identify the murder weapon, the direction of the velvet marks can be positioned, and secret embroidery can reveal old grievances. But the more I tried, the more frightened I became. A web named "Weaver's Gate" had been stitched since before I was born, weaving the salt case, family extermination, and palace silk orders into knots; the "weaver" who never showed up actually used the same stitching method as me. They told me to shut up. I want to take this thread apart, stitch by stitch, and put it back in broad daylight.
