Лю Янь
In 911, Liu Yin died and was succeeded by his brother Liu Yan. Yang continued to serve Liu Yan, and he suggested to Liu Yan that he should not commission army officers as prefectural prefects. Rather, Yang advocated that he select refugees from the Central Plains who were well-learned, first putting them on his staff to test them and then make them prefects, so that they could govern the prefectures well and benefit the people. Liu Yan agreed.
