Has Jinzhou BBQ ever won a national patent?

I do. Jinzhou barbecue restaurant has obtained the national patent. As the first patented barbecue shop in China, Jinzhou's barbecue skills have long been included in the intangible cultural heritage and almost become synonymous with the barbecue industry. Jinzhou is a prefecture-level city in Liaoning Province, People's Republic of China (PRC), which is located in the southwest of Liaoning Province and on the north bank of Bohai Sea.
