burst into laughter

Why, why am I so unlucky?
Why do I have a classmate like Harvey Chase? !
Briarose cried, ran to the corner of the back garden, and burst into tears!
She is really so wronged!
Harvey Chase just stood there, he looked at Liu Shanshan, and said coldly: "In the future, if you dare to provoke Briarose again, don't blame me, I will break your legs."
Harvey Chase turned around and ignored Liu Shanshan.
He asked a boy in front of him: "Hey, may I ask..."
"Ah! I don't know you!"...
