At nine o'clock at night on Wednesday, Mu Huaisheng heard a rigid creaking sound as he was rotating his head in an effort to loosen his stiff neck.
Sighing heavily, he leaned back in his chair, his head filled with thoughts concerning his work. He extended his arm to massage his stiff back and switched off the computer. He got up from his chair glanced at the nightscape from his window. Then, he took his car keys and left the office.
As usual, he conducted a habitual routine check of all the floors before he exited the building. Walking past the design department, he noticed that the lights were still on. It was not uncommon for an employee to turn off the lights, but neither was it uncommon for an employee to be working overtime. He walked into the department room, instantly spying a young woman buried in a mountain of work. She appeared frail, thin and weak.
