It was a great show!
This Secretary Zhang truly knew how to enact a great play for all the people witnessing it. His words, screams, and slaps could seem like he was reproaching this cousin of his, but he was in fact saving him.
After all, if this cousin of his continued further, and escalated the issue then his end would be a nice sleep with the fishes in the river.
Both Cui Xie, and the Director of the Auction House weren't people that could be easily offended, and even more so from a lowly manager that was working as a bouncer at the door.
For some reason he didn't doubt that should he leave his cousin's punishment in Cui Xie's hands, then even he would feel the pain of that.
Fortunately, he was quite the intelligent and capable guy, so he had already acted like this, helping that cousin of his dodge the storm ahead.
