All members of Lanxing Media chartered a flight to Sanya for team building. Of the forty-seven people, only Ji Heng, a low-level employee who supports the company's core business, was left behind. Colleague Qian Haoming sent a photo of an empty seat to ridicule him for being unsociable. Ji Heng, who had been robbed of his credit for many years, shut down his phone and fell into a deep sleep for thirteen hours. He didn't know that he was the operator of the Lingyun project and the core of the company's server operation and maintenance, and that he held all system keys and project source codes. During the period of loss of contact, all servers were paralyzed. Tens of millions of customers only recognized him for reporting, and the company was completely shut down. The management went back and forth all night to look for him. His colleagues who had ridiculed him in the past apologized one after another, and competing companies offered him millions of dollars in salary to poach him.
