《隋书·帝纪·卷三》
所以应立多少代祖先的庙，谁也说不清楚。祖先们是应同在一庙中连室而居，还是每人各主一庙，也没定准。
所以世数多少，莫能是正，连室异宫，亦无准定。
Therefore it is unclear how many generations of ancestors' temples should be established. It is also not certain whether the ancestors should live together in the same temple, or each person should have his own temple.
