How to simplify the washing bag for long-distance travel?

I think I have a say in this, because it's really a long trip. After three years of college, I went from Xinjiang to the northeast every time, and then returned to Xinjiang from the northeast. Once on the train for three days and two nights. At this time, I need a practical washing bag. The subject asked how to simplify the washing bag, so I can share my experience with the subject ~

First of all, the washing bag must not be too big, because the space in the suitcase or backpack is limited. I usually put it in my backpack because it is convenient to use and I don't have to take it back and forth from the suitcase. I usually put only five things in the washing bag, shampoo, facial cleanser, toothpaste set, razor and towel, which can be said to be the standard for men to travel. That's enough. This toothpaste set puts a toothbrush and toothpaste in a box, which is generally sold in supermarkets. If you use this, you don't need to buy a cup separately, because it will take up a lot of space!

If it is a lady, it will be more troublesome, because girls are different from boys, and they need to bring cosmetic bags ~ This is related to the place you want to go, except foundation, lotion and eyebrow pencil, and other things depend on the environment where you go. For example, if you go to Xinjiang in summer, you need to bring an extra sunscreen in your bag, but you don't need to bring this sunscreen in winter. Although the example may not be right, it means choosing what you want to bring depends on your place and time! And if you can, try to bring something dual-purpose, such as shampoo and hair care!

And be sure to use your own washing bag reasonably and fill up the space. If not, you can watch online videos. I remember teaching this ~

The above are some of my little experiences, which I hope will be useful to the subject ~
