The Seg Square was not closed, but closing. However, I've bought what I want.
When I got to the Seg Square yesterday afternoon, I surprisely found all of the gate of it was closed except a small one. I knew what this meant. The Seg Square was closing then, the small door was open just for the people who work there to leave the building. However, I wanted to get in and see whether it was really closing. When I walked through the small door, I was stopped by a securer. I was told definitely that the square was closing and I was not allowed to get in. Since I am not allowed to get in, I at least have to know when it would open again. So I asked the securer. He told me that it will be Feb.8. Hum... That's many days later. I couldn't wait for that day.
Ok, it was closed. Then I had to try another place to buy the router. Thanks to the God. The Baohua Building was still in business then. When I walked around the building, I found that the goods there was much less than those in the Seg Square. However, after a while of searching, I finally found what I was looking for. The bussiness was done in a flash. I paid 280RMB, 10RMB lower than the shop assistant offered, and I got a D-LINK DI-624+A. Then I says goodbye to the days that I might be asked frequently by Mark to get off to let her on when I use the internet.
