This scene was of utmost importance, where many foreshadows would be brought out into the light.
In the scene, Jia Xiaoqing went to look for Jia Shengnan, who was in the midst of a meeting in the military zone.
Jia Xiaoqing did not flare up on the spot, but waited till after the meeting. She immediately pulled Jia Shengnan to a corner.
The argument between the sisters grew louder and escalated. Eventually, Jia Xiaoqing even shouted without thinking, "You're really impressive, earning a living working for both sides. The traitor's money is easy money, isn't it?"
At once, Jia Shengnan's expression changed. She stepped forward and gave this idiot sister a tight slap.
This slap shattered the already strained relationship between the sisters. In a fit of anger, Jia Xiaoqing made a report against Jia Shengnan, placing justice before family.
Liu Wei never liked to fake her acting.
Hence, that was nothing less than a real slap in the face.
