The park (Haung Xing park) was a 10 minute walk from my hotel. On one side of the street are the sports fields which I didn't visit, but on the other side there are mostly trees and trails, plus a large lake. I went 3 times, but I would have gone every day if I could have, always before 8AM because of the heat. I went looking for kongzhu, but I found mostly groups doing Tai-Chi, Chi-Kung, and many other Chinese disciplines, sometimes using fake swords or fans. The vast majority were older people, but the ratio between men and women appeared to be pretty even. On my second day, asking for kongzhu and moving my arms as if I was playing, I found a group of about 7 people, including some women (yes, they play kongzhu). They were very kind and gave me some tips (using gestures). This was one of my teachers:
I was surprised that all their kongzhus had one-way bearings. After I demonstrated some top tricks with my Hollow Point, one of them grabbed the top, tried to rotate the tip and was surprised that it was fixed. So I gave him a bearing top, but he was still puzzled. Only when I gave him a one-way bearing top he seemed satisfied.
As I said before they recognized a whipping top, but unfortunately they told me that at that park there were none (I'm guessing it's more a winter activity).
On my last day I joined for a little bit a couple of groups that were doing ballroom dancing to Chinese music
. Farid and another Colombian were with me and they joined something like group hackey sack with something similar to a badminton shuttlecock. Great vibe all around the park (on some parts there were speakers with relaxing music).
