Can I buy a one-day ticket for North Music Festival for three days?

You can't. According to ponytail's query. Zhangbei Music Festival has been held for three consecutive days. One-day tickets are for one day, and three-day passes are for three days, so you can't listen for three days if you buy a one-day ticket. Music Festival is a temporary music performance, which has the necessary conditions for temporary existence. Many artists take turns to perform, with a large number of people.
