Remember that the garden's founder, Aw Boon Haw, was a staunch Nationalist/Kuomintang supporter, and I suspect that some of the Nationalist imagery in the garden was one of the reasons Li Ka-shing was so keen to bulldoze it post-handover. One example is the famous gate over the stairway that contained "Double Ten" references.
I personally believe the largest loss due to the redevelopment was, arguably, one of Hong Kong's most iconic pagodas. The white pagoda was a landmark and also highly ornate. It's a real shame that it wasn't kept along with the mansion.
You'll notice that the pagoda in this lower shot has the national emblem of the R.O.C on it. It's the famous blue sky with white sun emblem. Anyway, we'll finish off with some of the bizarre images that the garden was more famous for.
