"58度" should be 58%, not 58C...Did u guys simply translate it with Google translation? Coz 58C really sounds Google translation to me...Guess google thought you mean "58(攝氏)度“ :)
The red subtitle at the beginning at the top tells us more or less to remember that excessive drinking is bad for your health, and also underaged drinking is not allowed (in the case of Taiwan I think it's below 18).
