After paying respects to Heaven and Earth, it was time to enter the bridal chamber, which was quite different from that in the mortal realm. Both families would go together to the bride's grave, dig out the deceased's coffin, then carry it to the groom's grave. Next, they would dig a hole on the side of the groom's tomb, reveal the coffin, and place both coffins together, meaning combined burial. Afterwards, the parents of both families would refer to each other as in-laws and visit each other during holidays and festivals.
