Yesterday when I was heading off, I noticed that someone had trouble opening the door, then I immediately helped her, and asked her whether she was the newefm, and she said yes. She is originally from Kyrgyz Republic, central Asia. I noticed that she talked really fast. She told me that she was in Beijing for 4 years, and their place in BJ was super close to the dashiguan, like 5 min walk. And she can speak a little Chinese, but couldn't understand most daily conversations. Anyway, I'm glad that I approached her and introduced myself!
