According to market spot checks, there are many counterfeit Yunyan, especially famous brand "Hongtashan" cigarettes in recent years. The cigarette "Hongtashan" produced by Yuxi Tobacco Factory in Yunnan has four specifications: 84mm and 94mm hard box clamshell and 84mm and 94mm soft box. Market spot checks found that 84mm soft boxes were the most counterfeit products. The main points of identification are as follows:

1. Strip packing: the inside of strip packing and hard box has uniformly distributed colored fibers. In Chinese and English, the brand name of the strip is overprinted in red Phnom Penh, and the main pattern of "Hongtashan" is printed with golden peaks and clouds as a foil. In Chinese and English, "Produced by Yuxi Cigarette Factory in China" is marked in black regular script font. Recently, the product is pressed out with an anti-counterfeiting logo in the upper left corner. The illustration is as follows: It is clearly visible when it is irradiated by strong light. Hongtashan products are produced by the modern assembly line of winding, splicing and wrapping with international advanced level. Small packages and strips are packaged regularly, with clear lines, fixed external dimensions, small tolerance, firm adhesive joint, flat and clean appearance, compact plastic oil seal packaging and high gloss, and the sealing is heated and bonded by machine, which is not easy to open. The drawstring is self-sealing glue. Except the 94mm hard box is straight, the other drawstrings (including 84mm hard box, soft box and 94mm soft box) are semi-circular, located on the Hongtashan side with Chinese pinyin, and pulled counterclockwise. There is a 2-mm-wide matte oil adhesive tape at all adhesive seals of the box, with three-point adhesive seals on the side and dotted lines at both ends.

The fake "Hongtashan" cellophane has poor transparency and no luster. The cellophane is thicker than the real one, and there is a big gap between cellophane and the carton. Because the joint is glued, there are obvious wrinkles. It is easy to open the seal with a few hands, and the carton is irregularly glued.

2 boxes: gravure printing technology is adopted, and the fonts and patterns are clear and complete. The trademark is based on Hongtashan as the main pattern, with golden peaks and clouds as the background, with bright colors. The main pattern is printed in big red, and it is printed and overprinted in gold. The Chinese and English versions of Hongtashan are overprinted in red and gold, and the Chinese and English versions of China Yuxi Cigarette Factory are printed in gold standard font. The anti-counterfeiting emblem is printed on the upper left corner of the Chinese side of the soft package of recent products, which can produce the effect of ultraviolet photochromic. The hard bag is embossed with an anti-counterfeiting emblem in the center of the upper part, and the center of the pattern can produce the effect of ultraviolet photochromic. The "Phnom Penh" and "golden characters" in the pattern will show golden light under the irradiation of sunlight and light. Cut tobacco: The genuine "Hongtashan" cut tobacco is slender and even, with golden or orange color, glossy and oily, and no stalk. There is a certain proportion of expanded cut tobacco in cut tobacco, which is elastic when pressed, dry without mildew, and does not turn off when smoking. The color of cut tobacco of fake cigarettes is dark, black or red, and it has no oiliness and elasticity when pressed, indicating that there is no certain proportion of expanded cut tobacco, and some fake cigarettes have too many expanded cut tobacco, even mixed with cut tobacco heads and cut tobacco pieces.

besides the appearance, the most important identification of cigarettes is the internal quality. That is, according to the color, fragrance and taste of cigarettes, the authenticity is judged. The genuine "Hongtashan" cut tobacco is golden in color, glossy and oily, rich in aroma, harmonious and pure. It is prepared with special spices, with moderate strength, smooth throat, pure and comfortable aftertaste, and has a typical style of Yunyan. The counterfeit "Hongtashan" cut tobacco is finely divided and mixed in color, and some cut tobacco is dyed or mildewed. When smoking, it has peculiar smell: spicy, musty, earthy or peculiar smell of special spices, and it is easy to turn off the flame, which does not have the typical style of Yunyan "Hongtashan".

The identification method of Hongtashan cigarettes described above is also applicable to other products such as Yuxi, Ashima, Shilin and Hongmei produced by Yuxi Cigarette Factory in China. When making cigarette identification, consumers should make a comprehensive judgment, and make a correct judgment according to various aspects such as strip, box, cigarette, cut tobacco, color, fragrance and taste.
