A dead letter,

Theoretically,

The official situation is not optimistic,

Waving paper,

Falling clouds,

Paper evokes the soul,

Falling paper flies,

The name paper is raw,

Paper tiger,

Drill old piles of paper,

The pen is stuck in the paper,

Paper falling into the clouds,

Addicted to money,

Shredded paper,

Through the back of the paper,

Chew ink and spray paper,

On paper,

Oil paper gold,

Swallow paper and hug the dog,

Dye paper,

Shredded paper and ink,

The world is like paper,

Study old newspapers,
