Start with your smile, define a theme (generally for reference), and write a few poems, which should highlight the value of "smile" and rhyme at least 6 lines.

Snow covered the whole of China,

Whose heart is infected by blood?

The wind cuts the earth,

What are the people waiting for under the silver tree?

Red cheeks are the only warmth in this large area.

Her waiting,

Who got the heart?

Leave a stranger who just misses with a smile.
