What's the name of the place where the detention center keeps things? I want to send a banner to Qiancun's clothing department, but I don't know the name of that department.

That department should be the logistics in the detention center, but the gift-giving object (mentioned in the previous paragraph) can be said directly in the detention center. In order to show who is praising, it can appear in the content of the banner, such as saving money, safe and meticulous clothes! Finally, the signature name and date!
