I have discovered three more fascinating Chinese Characters that are being used as Given Names. Each character 汉字 is constructed from three occurrences of a single radical.

晶 jīng ≅ crystal/bright/radiant. The radical is 日 which means Sun.

磊 lěi ≅ Sincere/Great/Massive/Pile of Stones. The radical is 石 which means Stone.

鑫 xīn ≅ Symbolises Prosperity. The radical is 金 which means Gold.
