The Dr Sun Yat-sen and Nanyang exhibition will open on Friday at the Hong Kong Museum of History in Tsim Sha Tsui. Dr Sun once said that 'the overseas Chinese were the mother of the 1911 Revolution'. The overseas Chinese in the Nanyang, or South East Asian, region were very active in raising funds, preparing propaganda and staging uprisings in support of Dr Sun. In the early 20th century, Dr Sun's Tong Meng Hui (United League) had established more than 20 branches in the Nanyang region and Singapore was designated as the regional headquarters. The revolutionary centre was then relocated to Penang, Malaysia, where the Huanghuagang Uprising in Guangzhou was planned. The exhibition, running till June 20, will feature episodes from Dr Sun's time in Nanyang, comprising more than 80 photographs, an illustrated panel text and a documentary video.
