At the initial meeting between Qin Tian and Xu Junwei, a method for exchanging information was agreed upon.
Unless there's an emergency, on the last day of each month, if a red cloth is hung at the window of the Tianzi private room at Ming Yue Teahouse, it indicates that Xu Junwei wants to see him, and Qin Tian should go to Ming Yue Restaurant that night.
If there's no white cloth hanging at the window, then Qin Tian doesn't need to contact Xu Junwei, and he should continue to lie low.
On the last day of this month, Qin Tian walked out of East Han Academy and saw a red cloth wrapped around the window rack of the Tianzi room in the alley behind the Ming Yue Restaurant.
For the first month, Xu Junwei unexpectedly had something urgent.
That night, Qin Tian arrived at the Tianzi private room.
Shortly after, Xu Junwei arrived late.
