Guardian:
房间的积灰不厚, the accumulated dust in the room isn’t thick
沈教授，你确定要这房子吗？Professor Shen, do you definitely want this house?

Me:
火车出发时十点三分，所以我们一定要直到差两分十点到了火车站。
我的房间里反正有太多书，地震的时候比较可怕。

给大家周知，I will be traveling a little and so tomorrow's post will be delayed by about 12hrs from the usual posting time. 但是, the post itself is written up, so if anyone wants to post it in my stead around the usual time, let me know (if possible within the next two hours or so) and I'll send you the content. Either way works!

(also comment replies shortly，不好意思啊)
