The "Secrets of Growth" carnival, the fourth of six legs of the QBABY Children's Balance Bike Open, a brand event hosted by Yangcheng Lake Peninsula Tourist Resort (YLPTR), kicked off at Octave Community, YLPTR on Sept 2.

The new session was greatly different from the previous ones. The cycling rivalries included those on flag stone paths, imitating that in Paris–Roubaix, a globally renowned cycling event in northern France.

Apart from that, the event incorporated more parallel events, where the children and their parents enjoyed delicious food, reassembled dinosaur fossil models together and learnt knowledge on healthy food parings from a nutritionist.

It is noteworthy that each of the children who finished the cycling rivalries received a specially designed medal, a bear-shaped one with a "K" on one side, meaning "Kids Keep Knowledge".
