In the middle of the night, Bai Xia Fang received a call from his employees. At first, he did not want to pick it up. However, the phone was still ringing after a long time. He could not help but pick up the call.
"President Bai, we have a big problem here." The person said.
"What is the problem?" Bai Xia Fang was in a bad mood.
"President Bai, the proposal for the International Conference had been missing from our server." The person on the call informed Bai Xia Fang.
"What?" Bai Xia Fang stood up getting out of bed. "What is this happen?"
"We are working on the proposal and suddenly the server stated the file is not found. We called the technician to take a look. However, the technician told us that the file had been deleted. And the deleted file could not be recovered anymore." The person explained.
