Don't think that there is no such wine in China. Many brands have the very decorative wine you mentioned, and the price is about 1000 yuan. I forgot the specific brand, and I have never seen a rifle or pistol. I don't know what kind of gun you are talking about. As for trademark patents, because you are imitating a gun (whether true or not), it looks very difficult. You should check with the Industrial and Commercial Bureau and the Liquor Monopoly Bureau.
Finally, I wish you success. I'm also looking forward to the launch of this wine, but it seems to be imitation. In recent years, I have seen too many products similar to edge balls, and few of them have a long life.
