While driving on the road, Ge Dongxu called Lin Kun and asked him to notify the person in charge at the hotel that he was about to arrive at Kunting Hotel and needed some assistance from the front desk staff.
Although Ge Dongxu was a major shareholder of Kunting Hotel chain, besides Lin Kun and Yue Ting, very few people in the company knew him, so he still needed Lin Kun's help to communicate with his own hotel.
Of course, Ge Dongxu could have directly shown his National Security credentials, but those credentials were ultimately too sophisticated; ordinary people might not be able to discern their authenticity. A young man rushing in and presenting such a document could easily cause suspicion or even panic at the front desk, so it was simpler and more convenient for Lin Kun to make the call.
After all, he was a major shareholder of the Kunting Hotel chain!
