Our host this time was Prof. Li Xiaoming who is the head of department. He also leads a large and active Research Group in Networks and Distributed Systems, so our course was on a subject dear to his heart and we got on very well with him.

We taught almost the entire contents of 10 chapters from our book in two weeks, lecturing for 2.5 hours every evening to 45 students on the three-year master's degree in Computer Science at Beida. They were very well-educated and enthusiastic students and we very much enjoyed teaching them.

The classrooms in CS at Beida are equipped with data projectors and the building has wireless internet connectivity, so we were able to teach using our laptop computers for presentations and online demonstrations.
