¥180 RMB per Catty of roast lamb? That is more expensive as it is in the U S. In the U S , you can get 1 pound of roasted boneless lamb leg for $17 USD, which is equivalent to ¥163.5 RMB per Catty ($17 per pound × 7.27 RMB per USD × 1.323 pounds per Catty ≈ ¥163.5 per Catty). What is so special about that roast lamb??? 🙂
