The next morning, Mo Ting dragged Tangning out of bed for some early training. As Tangning's fight scenes following on would be more dangerous, she decided she'd tell him about the scenes and then practice with him to see if he had any suggestions.
In reality, as soon as Wei An notified Tangning to prepare for dangerous scenes, most of the crew assumed she'd take a long time to adjust. After all, she had no foundation in martial arts. But, surprisingly, all she needed was one night, and she was able to do what she previously couldn't.
So the crew realized, they could never judge the 'Future Tangning' based on the 'Current Tangning'. Because, apart from the strength of her own perseverance, she also had a capable manager - Mo Ting.
Elder Mo continued to remain on set. After his identity was revealed, he would appear on set dressed in traditional clothing as he waved his fan and gave Tangning pointers in her acting.
