How many Chinese are vegan?

Can you provide me with an estimate of the number of Chinese individuals who follow a vegan lifestyle? It's intriguing to ponder the prevalence of veganism in such a vast and culturally diverse country. Is there a growing trend towards plant-based diets among the Chinese population, or does it remain a niche practice? What factors might be driving or hindering the adoption of veganism in China? I'm curious to understand the cultural, economic, and social dynamics at play here.
