Hi!
So today I went there to have a look
Here is a view of the building. From the outside, it was totally not obvious that something was happening inside:
I went inside anyway, and there were many people waiting on the first/second/third floor. I guess they were accompanying the younger players, and were waiting for them to finish playing. Here are some picture of the first and third floor floor. There was some sort of Go shop as well (in fact, that was not a Go shop) and I somehow befriended with the people working there:
So if was not possible to enter the playing room, and those area were every were waiting had no AC, it was very hot (as expected from NanNing in August), so I was not really considering to stay longer, call it a day and leave.
But then, I remembered
wolfking had mentioned some traditional Chinese garden on the roof, so I found my way up to the top, and here are some more pictures:
And then, in one of those pavilions, I noticed some two persons apparently playing and official game. I could not (dared not) to enter, but managed to take a few pictures from the outside:
At least I would had something to show
But then, since I had befriended with the people from the shop on the first floor, they provided me with a "spectator pass" (they asked me if I would prefer a "Player pass" but I went for the first one

) so that I could try to enter the main playing room. Equipped with that sesame, I felt brave enough to try to force the security check. The security team were not deceived by that, but as I explained I just wanted to have a quick look inside and take some pictures, they let me inside. So here is the main playing hall (most of the 2nd? round games were completed already):
Then I went back to the roof, the game was over, so for those interested, the 2 players were:
And there were two other players reviewing their game:
So those 2 matches were team GuangDong (where GuangZhou/Canton is located) versus another team that I cannot identify.
Finally, I was able to chime in the conversations a groups had on the roof, but for a very short time. And now, I realized that one of those persons was
WANG Hui 5d that was mentionned by
wolfking above. I regret I did not realize that at the time, otherwise I would have asked for a selfie, but I quickly shied out of the conversation, because I am not that confident when handling a conversation in Chinese
Anyway, that was fun. All the pictures are in
