Map.
The map here can be a local cardboard map or a local mobile phone map. However, Zhu Xiao suggested that both of them should be prepared and take a paper map with them in case the local signal is bad. Moreover, mobile phone maps must be downloaded offline, so that there will be no embarrassment and helplessness even if there is no network.
Local temperature, buses, subways, etc. Of course, the temperature in different tourist destinations is different, and even the temperature difference between day and night is very large, so it is necessary to understand the local temperature changes this season. In this way, you can prepare some warm clothes and a portable blanket to prevent freezing into a dog. At the same time, you can prepare a little change or coins with you, which is especially convenient to go out by bus.
Toilet supplies.
You can usually prepare some travel cosmetics and toiletries, or buy some bottles, and put a proper amount when you go out, which is convenient and avoids being overburdened during the trip.
Food.
Food is inevitable when you are away from home, but it is expensive, unsanitary and unaccustomed. We can put some dry food in our backpacks, such as dried fruits, compressed bread and other high-energy foods, and prepare a traveling water cup at the same time.
Charger.
In this society, electricity is indispensable, so we must install chargers, including mobile phones, SLR, and even computers (computers are not needed). This will not only leave beautiful scenery, but also make the journey not boring.
Simple medicine.
It is inevitable to stumble when going out, especially some friends like to go to mountainous areas, plateaus, deserts and other places, and they can bring some anti-inflammatory drugs, traumatic plaster, antidiarrheal drugs and so on. You can help others and make new friends when you don't need them.
Card or credit card.
Sometimes it is inevitable that the travel expenses will exceed the plan. You can bring your bank card or credit card to avoid the embarrassing situation of "being alone" in a foreign country because of economic problems. So it's safest to bring your bank card and credit card.
