What does the joke "Ilyichiva Mopolov Krilavic" mean?

A Russian got lost in the trip. In the evening, he went to a small village on the border of China. It is snowing all over the sky outside He was too cold to stand up, so he knocked on the farmer's door and asked for accommodation. An old lady asked loudly in the room, "Who are you?" The Russian said, "ilych Wa Mopolov Krilavich!" "There are too many people!" The old lady slammed the door that she had just opened.

"ilic Va Mopolov Krilavich" is a Russian name. Because the Russian name is divided into three parts, the old lady naturally thought it was three people, so she said, "There are too many people." Close the door.
