I add a collion box in a blueprint actor and put the actor to the scene.
When a particle system went into the box,the BeginOverlapEvent was not fired.
Does anybody know the reason?

Check the collision preset of the collision box. You need set it to overlap (I am not sure which one needs to overlap tho, maybe try it 1 by 1) and tick to generate overlap events.
