Today we visited Peking University. Early in the morning we arrived at the gate of Peking University, where the students gave us a warm welcome. The students showed us around and explained many things to us enthusiastically. First we went to the library. We saw many books and quite a number of students were absorbed in reading. Then we visit the lab building. On the campus, we found here and there students studying under the trees. The students gave us a lecture in the afternoon. Time passed quickly. Before we knew it, it was time for us to say good-bye.
