The top of the stove is well painted. The top of the stove smells good, because the top of the stove is the first soy sauce extracted after soybean fermentation, so the taste is the most mellow and rich.

Liu Zaoji is the founder of "Zaoding" brand and has been operating Zhengguo Zaoji Soy Sauce Factory for more than 30 years. From brewing craftsmen to entrepreneurs, he always insisted on natural brewing with ancient methods. Liu Rongbin, 33, inherited his father's business and took over the soy sauce factory in 2007, inheriting the traditional craft of ancient brewing and natural drying, aiming to provide healthy and original soy sauce for more consumers.
