In 1909, the Qing Dynasty government initiated the construction of a western-style "Hall of water" but plans stalled due to budget restraints, making it the only unfinished building in the former royal palaces. The Ng Teng Fong Charitable Foundation has agreed to donate 100 million yuan ($14.9 million) for research, protection, training and exchange programs for Hong Kong youths. (Photo/VCG)
