Under Emperor Taizong of the Tang, an imperial decree ordered that on the death anniversaries of previous reigns, incense be offered and a vegetarian feast be held at Zhangjing Temple. Emperor Zhongzong decreed that on the death anniversaries of the seven imperial reigns, vegetarian feasts and incense offerings be held in the inner palace. Emperor Xuanzong decreed that whenever monks and Daoists encounter a national mourning day, they should proceed to Longxing Temple to practice the Way and conclude the fast. Emperor Xuanzong (r. 846–859) decreed that on the death anniversaries of the successive sage emperors, all should proceed to Buddhist temples to offer incense in accordance with the ancient statutes (this was just after Emperor Wuzong's suppression of Buddhism). An imperial decree also directed the prefectures and commanderies that when offering incense on national mourning days, no one was permitted to bring wine or meat into the temples.
