Why is Moutai so popular?

I'm curious to understand, why exactly is Moutai, the famous Chinese liquor, so incredibly popular? What are the key factors that contribute to its widespread appeal and reputation? Is it solely due to its unique taste and flavor profile, or are there other factors at play, such as cultural significance or scarcity that drive its popularity? I'm eager to gain a deeper understanding of the reasons behind Moutai's enduring popularity.
