《梁书·列传·卷五十二》
遇上初一、十五、大祥小祥的祭日，或是忌日，可以临时设置一张小小坐榻，安放几案和坐席，衹要置办几样素食，不要用牛羊猪祭奠。
朔望祥忌，可权安小床，暂设几席，唯下素馔，勿用牲牢。
When encountering the first and fifteenth days of the lunar month, the major and minor auspicious days, or the anniversaries, you can set up a small couch, a table, and a seat, only prepare some vegetarian food, and do not sacrifice cattle, sheep, or pigs.
