A strange new drink came out from Guangdong

It's plum soda. The first taste is strong carbonation and plum flavor.
After swallowing a sip, the sensation left in the esophagus is hard to describe, but it's like that lingering feeling you get when drinking something like Hwalmyeongsu.
It's a drink while you're sipping it, but after drinking it, it feels like you've eaten a Halls lozenge? I think they've made something quite fascinating.
