Judging from the situation you described, it should be the northern county. Seafood barbecue is indeed a major feature. We specialize in oyster seafood here, but other varieties are also doing well. The consumption of seafood in the mainland is high. You should make sure that those people in your county have enough spending power. Seafood is not well preserved, or there is no money to earn. It is suggested that under the premise of making all kinds of barbecues for the public, some seafood varieties with relatively low price and long preservation time should be made. Southern customers like to sit outdoors, and the room is relatively narrow.
Try not to be partners, it is difficult to unify opinions, and in any case, everyone is selfish in front of interests, don't break up, and it is not easy to recover the money invested.
