With the sun rising in the east ,our classmates and I arrived at the gate of Tsinghua University to visit the campus of the Tsinghua University.At first,we visited the library which was very quiet.It's very big, the number of the books were over 10 thousand,many people were reading the books there.After that we went to the storey of labs .The trees were standing around the storey. At 3:00p.m. we had a lesson and the teacher of Tsinghua University told us the history and advantage about it.With the sun setting in the west ,we had to leave the campus of the University.At 8:00 I was sitting in my room to keep my dairy.I put it ，I 'll never forget the memorable day when I visit the Tsinghua University. In a word ,I will study hard to be a student of Tsinghua University.
