Xie Zhiming grew even more worried when he thought of that.
Anyone else would feel panicked when they find out that they have been watched for a long time.

Xie Zhiming finally calmed down upon returning to the room in the teahouse. He took out a few old envelopes from his pocket and said, "It's all here."
Jiang Tingxu paused for a moment before approaching, saying, "Uncle Xie, I'll read them then."
Xie Zhiming nodded. He said, "Go ahead, they were written by your dad."
The last few letters could really be considered the only things left behind by Jiang Tingxu's father before his death.
The two of them were once comrades-in-arms, so the letters were basically about Jiang Guoyu reminiscing about the past and his hopes for the future.
