Zhou Niannian first called her brother, Zhou Huainan. Zhou Huainan was a special police officer who was in charge of the safety of the leaders at the Great Hall. When he received his sister's call, he didn't alarm his parents or even his wife and daughter. He returned to his study quietly.
He turned on the phone and entered the satellite system. He locked onto the capital city and entered the street number. Soon, he knew where his sister was.
She could go home through this route, but it was quite far. How was Zhou Niannian going to take a detour home?
Zhou Niannian seemed to have guessed what her brother would ask. She held the steering wheel firmly with both hands and occasionally looked at the car behind her through the rearview mirror. She pretended that nothing was going on and continued driving.
