What are the four-character idioms that contain cows?

Cowherd and Weaver Girl,

I am a skilled worker,

A lot of sweat,

Bull's head and horse's face,

Play the lute to a cow,

Without cows,

Ghosts and monsters,

Nine Niu Yi hairs,

Hang a book in the corner,

Leading the cattle in the field,

Five cows cross,

Pneumatic bullfighting,

Drill a dead end,

A little test,

Mud cows into the sea,

Cow clothes cry,

The rhinoceros looks at the moon,

Cows and horses,

A dime a dozen,

Old calf,

Niuhuang Goubao,

It's drizzling,

Air to air,

As brave as an ox,

Cows are tall, horses are big,

Trade sheep for cattle,

The speed of snails,

Ask a cow to know a horse,

After the chicken's mouth,

Wood is rarely used in summer.
