If you want to buy authentic Shuangliu Mom's rabbit head, you have to go to Shuangliu Mom's rabbit head store to buy it. Everything else is fake. It's stated in other people's storefronts. Apart from Shuangliu's main store, the only branch in China is in Beijing. Mom's store has a special take-away window, and 52 yuan has a bag (containing 1 rabbit heads, and a vacuum bag is charged in 2 yuan).
