There was a short message saying that there would be a meeting tomorrow, and the theme was love, the purpose of carrying on the family line, and the time, place and people behind it ... what is this?

Tomorrow's exam, topic: love, purpose: to carry on the family line, content: love is in the wild, location: on the grass by the river, requirements: bring your own straw mat, don't wear trousers, don't wear a cloak, work in pairs, move quickly and pose handsomely. Send it to eight best brothers, and you will be impotent in three days.
