Zhang Heng browsed several other hot posts and registered an ID called Saturn 5. He then shut down the computer, and left the Internet cafe. The whole process only took him less than twenty minutes, and when he returned home, Tian Tian was alone jumping on a rope in the backyard. Grandpa was leaning against the courtyard door, looking at her. He looked a little worried.
Sensing unrest, Zhang Heng put on his slippers and walked to his grandfather.
"Do you remember taking Tian Tian with you last summer holidays?"
Zhang Heng nodded.
"At that time, she was very lively, running around the house behind you. In fact, when I saw her a month ago, she was still very normal, jumping up and down all the time. But after that, she somehow became terrified of communicating with other people."
"What happened in between?" Zhang Heng asked.
