When we collect it, the first thing is to clean it up. Then, classify.
Extra thick and heavy clothes can be put in vacuum bags. How's this? It saves space.
Then put it on lighter clothes, fold it, and keep it in the sorting box. As for some suits and the like, or some clothes that need to be neat, you can fold them down and then gently put them in some boxes for preservation.
And those shoes and boots need to be cleaned, dried and stored in shoe boxes.
Silk clothes and pure wool clothes need to put some insect repellent to avoid being bitten by insects and mildew.
Generally speaking, different clothes should be preserved in different ways. In this way, it can be taken out in the second year, properly dried and sorted, and then it can be used again.
