One background is a beautiful joke about the Republic of China.

He has been a groom three times in his life. The first time, he was a mountain king, robbed the landlord's son as his daughter, and simply forced the young master to be the wife of the village.

the second time, he joined the revolution, took his young master to the chief to get his notebook, refused to give it, and simply drew one himself;

for the third time, they were wrestled and knelt side by side. The rebel side asked them to kowtow, but he refused. The young master smiled and sang "Worship Heaven and Earth"-two heads knocked down and never lifted, and they finally became husband and wife for life.
