Cui Guofu was a scholar and poet well known for his magnificent 5 characters per verse short poem. After his demotion to Jingling, Cui Guofu took life fairly easy. Even though Cui was many years older than Lu Yu, both men shared the same interest in tea, literature, and poetry. As such they became good friends soon after they met. During this period, Lu Yu stayed with Cui Guofu and assisted him in his administrative tasks. The two of a kind spent much time traveling, drinking tea, and writing poems, and they co-authored several books on poems.
