Generally speaking, this kind of scene is shot using camera angles; Tang Qian's hand would swing down while Dong Xin Yan tilts her face accordingly, avoiding an actual hit.
But unexpectedly, after Tang Qian's hand swung over, a crisp "slap" sound echoed. Her slap really landed on Dong Xin Yan's face.
Everyone present was stunned, and for a moment, no one reacted, as if the air had frozen.
It was Tang Qian who spoke first, looking at her hand with astonishment, as if she hadn't expected the slap to actually land. Blinking her big eyes full of apology, she said towards the director, "Director, I'm sorry, I think my hand slipped."
Tang Qian's voice quickly pulled everyone's consciousness back. The director snapped back to reality, instinctively wanting to say it's alright, but when his words reached his lips, he realized something and couldn't help but look at Dong Xin Yan.
