When I bought Yunyan in Kunming, there was a white box with the words "trial production" written on it and "for expert evaluation only" next to it. How much is a box?

Cigarettes supplied by Hongyun Honghe Group are not sold externally. If you buy genuine cigarettes (there are many cases of counterfeit cigarettes), it is the trial-produced cigarettes of Impression Yunyan. It's not produced at all now. The production date should be around 2003-2004. There will be no trial-produced cigarettes after Impression Yunyan is officially listed, so the price should be more expensive now. The price of Impression Yunyan in Kunming is 600 yuan/bar, because there are few trial-produced cigarettes.
