Lian Xinying had just stepped into the office and didn't particularly notice the smell.
After Kim pointed it out, Lian Xinying could smell it too; it was indeed a bit pungent.
"I'll go open the window; maybe I haven't been here for a while, and the windows weren't ventilated." As Lian Xinying went to open the windows, Kim turned on the air purifier in Lian Xinying's office.
After Lian Xinying opened the window, she went back to her chair and sat down, only to find Kim almost crawling into the air purifier.
"Kim, what are you doing?"
"Sister Yingying, I suspect the plastic bag on the filter inside wasn't removed..." After Kim said this, Lian Xinying quickly walked over.
"How did you figure that out?" Lian Xinying didn't understand this.
"I saw a meme on Weibo! Many people bought air purifiers and didn't know the filter had a plastic bag around it. If you don't remove it, it doesn't work at all..."
Kim actually had no idea how to determine it; she was just curious.
