What does good friend Allen mean?

The ancients called the life of husband and wife "Dunlun", which means Dunlun, and also called "the gift of going to the Duke of Zhou", that is, they thought that the life of husband and wife was an old rule set by their ancestors, without any meaning of "filth and impurity".

In the Han Dynasty, there was a man named Chen Bojing. Before sharing a room with his wife, he should check the zodiac, choose an auspicious day of the zodiac, send a maid to inform his wife repeatedly, and then go to his wife's room.

There was a man named Xue Changxu in the Tang Dynasty. Every time he intends to get along with his wife, he is sure that the maid will tell him again and again, and then he will come by candlelight, chat in his wife's room, have tea, and then take a long leave.
