Tai-Chi series is the series that made Ju Ming famous internationally. He learnt Tai Chi because he felt he was too thin at that time. After that, he used the Tai-Chi post as the base for his sculpture. Later, he tried to smooth out the Tai Chi post and made it more round and mixed.
The first one is like the one we have in Exchange Square. The second one is more modern and its ideas was come from a piece of wood log. The last one showed his final work on Tai Chi series as it is like an arch, which you cannot see the exact Tai Chi post but you can feel it.
