First of all, there is a very important sentence in the military, and that is? The soldiers and horses didn't move food and grass first? In fact, this sentence is also very practical when ancient people went out of the city, because the ancient road is not like the current road, so it is difficult to get out of the city. In addition, in some places, you don't know whether there is a family or an inn where you can rest for dinner, so food is very important for the ancients who are going to travel far away. As long as you are going to travel far away, you need to prepare some dry food.
Followed by silver, it is the second most important thing besides food. Whether it is modern or ancient, as long as you want to travel far away, you must bring enough money, otherwise you will be in big trouble if you have no money halfway. In ancient times, trading was not as convenient as it is now. You can scan directly with your mobile phone and transfer money directly. At that time, you still need to exchange actual silver, so it is very difficult if you don't have enough money.
In addition to eating, there are carriages and changing clothes, which are necessary for long-distance travel. After all, the road at that time was not easy to walk, and certain means of transportation and clothes were needed.
