Raw Material Selection: Yellow cattle sourced from large-scale domestic beef bases are adopted. 

The beef features higher protein content and lower fat content. Pure Salt Curing: Naturally air-dried with

 a clean ingredient list. We use Sichuan well salt, which contains approximately 0.1–0.7 grams of calcium

 per 100 grams, along with various minerals and trace elements including calcium, magnesium, potassium

 and iron. Compared with ordinary sea salt or lake salt, Sichuan well salt is richer in natural minerals,

 delivering a mellow flavor and exceptional quality. Cut Selection: We select beef from the hind leg 

(knuckle and topside are the optimal cuts), which boasts abundant lean meat and minimal fat, featuring

 firm texture and dense muscle fibers.
