I think it's premixed. Wal-Mart cannot sell cocktails! I recommend Bacardi rum premix, 275ML/ bottle, 4.8% strength. Although it is a premix, don't mix it with other drinks, because Bacardi Bingrui itself is a mixed wine, so it is no problem to drink it directly. There are seven flavors: fresh lemon, vibrant lime, romantic peach, passionate grapefruit, mysterious wild berries, brilliant oranges and cool blueberries. (Attached: Picture of Bacardi Ice Sharp)
There are other Baidu pictures I can see, so I will not post them.
I hope this helps.
