The selection of tobacco leaf materials has shifted from a traditional formula model based on numerous high-quality ingredients to a model that incorporates regional diversity, varying grades, and a small proportion of locally distinctive materials. The blend formula for the cigarette leaves comprehensively considers the balance of the chemical indicators of each tobacco leaf, meticulously crafted to explore the application value of each ingredient. The flavoring and fragrance are crafted using natural herbal essences to complement the inherent aroma of the tobacco, resulting in a harmonious, delicate, and lingering fragrance that highlights the distinctive "smooth aroma" style.
