Chewing
槟榔 is a major cultural habit in Hunan, Hainan, and Taiwan — it gives a mild stimulant buzz like nicotine. The WHO has classified betel nut as a Group 1 carcinogen, and oral-cancer rates among heavy chewers are alarming; mainland China banned
槟榔 ads in 2021. The standard pinyin is bīnglánɡ; you may also see bīnláng in informal use (Taiwan pronunciation).
