Nan Feng simply asked, "Brother Wen, why don't you guys label the purpose of each room? For example, where the archive room or conference room is? This place is so big, how does one find them?"
Wen Qiang chuckled, "You don't know because you're new, but we that have been working here for years know. We did use plaques to label the rooms but they were blown away by strong winds a few months ago, and we haven't put them back."
So that's the reason.
They walked a bit further, and Wen Qiang opened one of the rooms, "We're here."
Nan Feng followed Wen Qiang inside, but contrary to what he said, there wasn't dust, just the distinct scent of old ink.
"See, I told you the dust in here is terrible. You didn't believe me," Wen Qiang naively took out an application of a guild withdrawal from one of the shelves and handed it to Nan Feng, "This is the latest one, take a good look."
Nan Feng opened the withdrawal document.
