I'm wondering, regardless of Xiao Huo, whether the boss and fox have met somewhere else.
The first is that both the boss and fox have seen Xiao Huo (provided that both of them still have ozt alive)
The second is that the boss has seen Xiao Huo, but the fox has not arrived in Hong Kong yet.
The third one is that none of them have ever seen Xiao Huo. ． A long time ago the boss met fox
