First of all, most music festivals are located in remote areas, ensuring sufficient venues, which makes it inconvenient for people to take things, and many people will choose to buy them elsewhere; Secondly, there is no time limit for stalls selling things outside. You can buy it as long as someone sells it. Finally, remember to bring enough cash, because the venue of the music festival is far from the urban area, and there is no signal easily, which makes WeChat payment and Alipay payment unusable.
