What do you need to prepare and how many sets of clothes do you need to bring to travel with the group easily?

Check the local weather forecast in advance, you should probably be able to wear spring and autumn clothes, and it is convenient to leave one or two small coats with T-shirts and pants. Because jeans are versatile, you don't choose clothes, you need to bring toiletries. You can go to the supermarket to buy that kind of travel clothes, which saves a lot of space. Your ID card is definitely necessary. If you have a student ID card, you must also bring your bank card and cash (if it is convenient to withdraw money in the urban area, there will be a handling fee). It may be troublesome to withdraw money in the suburbs, so I suggest you bring more cash or a mobile charger, because mobile phones are very expensive now, so you must bring a mobile charger when you travel. If you travel, your camera must be a must, not to mention your home key and your mobile phone. In the coastal city of Qingdao, you can bring some beach surfing equipment, slippers and shorts. . . . Have a nice trip!
