Chengdu, Guangzhou, and Haikou represent key cultural hubs in southern China, with Haikou being notable for its betel nut consumption, a practice deeply rooted in local tradition. Despite health concerns and bans in other regions, betel nuts remain popular in Hainan, where over 2.3 million people are involved in the industry, contributing significantly to the local economy. However, post-pandemic economic struggles have led to decreased sales and increased competition from younger sellers entering the market, while health warnings about the nuts may begin to impact their popularity.
