What are the four major folk songs?

The four kinds of folk jingles are as follows:

1, four major grievances: digging tunnels, squatting in prison, cuckolding, and writing materials;

2, four scary people: take the black road, meet a new grave, the cat calls the nest, and people call the soul;

3, Siping: big girl face, fine porcelain bowl, painting table, glass plate;

4. Four waves: people laugh, horses bark, donkeys bark, and dogs break their legs;

5, four straights: carpenter's ruler, bricklayer's line, spinning floral axis, carving arrows;

6. Four evils: swearing at the dumb, beating the blind, kicking the widow's door and digging the grave of the tramp;

7, four happy events: the wind flag, the top water fish, the newborn calf, and the shouting donkey;

8. Four major losses: swearing at the dumb, smashing the widow's door, kicking the lame, and digging other people's graves;

9, four major flaws: the first leek, the new lotus root, the newly married daughter-in-law, the child's hand;

10, four orders: geese flying alone, grass on one side, bachelor pillow, rhinoceros horn;

1 1, the four major slowness: the car enters the station, the boat goes ashore, the tortoise climbs the mountain, and it is embarrassing.
