There is no most authentic statement. Moreover, Hengshun is not even a registered trademark, so it is not proprietary, which means that anyone can call themselves Hengshun (look carefully at the bottle sticker, there is a Chinese character written in the small circle next to the two big characters "Hengshun" "vinegar" instead of the trademarked ? symbol). It is generally believed that the best brand of Zhenjiang vinegar is Jinmei brand, while Jinmei brand and Jinshan brand are the same product, and Jinshan is a trademark used for export products. Maybe my memory is reversed, but it must be related to these two brands.
