Niulanshan aging is Luzhou-flavor liquor, which has the same taste as Wuliangye. Luzhou-flavor liquor cannot be called Erguotou. You can look at the packaging of Niulanshan wine. If there is absolutely no Erguotou on the aged packaging, then Erguotou is a fragrant product, not a taste, and the two are not fragrant. Niulanshan is just a trademark of liquor, which can be used in that liquor.
