Haha ~! Not a family. I was confused at first, just like "Jiujiu Duck" and "Jiujiu Duck", they all have their own chains. The trademark of Zhou Heiya is "delicious", and the top of Zhou Ji black duck is "delicious"

Zhou Ji Black Duck Headquarters Address: Ganglu, Jianghan District, Hankou, Wuhan Zhou Heiya is located in Jason Wu Road, Wuhan. I don't know which is more authentic. I only met Zhou Ji Black Duck in Beijing, but my friend brought it back to Zhou Heiya from Wuhan. I didn't know it was not a brand until two months ago.
