《北齐书·列传·卷四十》
按照过去的惯例军民要演习田猎，每年十二个月，每月围猎三次，唐邕认为这样搞得人马疲困，就奏明皇上，请求改为每月两次。
邕以军民教习田猎，依令十二月，月别三围，以为人马疲敝，奏请每月两围。
According to the old practice, military and civilians will practice hunting. Each month of the twelve months of the year, they will hunt three times. Tang Yong thinks that this will exhaust people and horses, so he played the emperor and asked to change it to twice a month.
