Describe a clip of a person laughing.

Bao Xiao's favorite book is a joke book! Buy every issue, every issue does not fall!

On one occasion, Bao Xiao, who just bought a book, couldn't help but open it and read it on his way home!

Just read two lines, Bao Xiao's mouth pursed, her mouth slightly raised, and the smiling muscles on her face involuntarily raised. "Hee hee!" Bao Xiao's nose was buzzing softly. Slowly, Bao Xiao's mouth opened wider and wider in Zhang Yue, from a crack to a circle of teeth. The muscles on his face are high, with a book in his hand, his shoulders shaking gently and his eyes bent into a crescent moon! Finally, "haha. . . . . . "Bao Xiao with a book in his hand, shoulders shaking violently, head held high, exaggerated smile mouth wide, eyes cracked with laughter, eyes moist. Wow! Tears are laughing! The charm of joke books is too great!

Original work, I hope it's not a misunderstanding.
