What did whip mean in the old society?

Describe the sufferings of the poor in the old society. Sing a folk song for the party. The lyrics of this song were written by Yao. /kloc-one summer night in 0/958, he wrote the poem "Sing a Folk Song for the Party". Only the word "whip" in the second paragraph, Yao thought for a long time. The first draft is: "In the old society, three mountains crushed me ... knocking down the mountains to be the master." After repeated thinking, Mr. Yao felt that these "three mountains" were not enough. He turned to a picture book and saw a fat landlord with a whip on it. He was immediately inspired. He felt that it was more vivid to describe the sufferings of the poor in the old society with "whip" than "three mountains", so he immediately changed his pen to "whip me in the old society ... and beat the enemy with a whip" The poem was published in the column of Shaanxi Literature and Art magazine "General Line Poetry Publicity Sheet", signed as "Jiaoping", which is homophonic with Jiaoping Coal Mine.
