The wild and semi-wild population in reserves in Hainan Island has growed up to more than 2000 now from 44 in 1970s. According to an survey in 2007, the captive population was 81 in China, also most in Hainan Island deer farms. In mainland China there were only 9 at Shanghai Wild Animal Park and 4 in Guangzhou Zoo, but I'm not sure wether Shanghai WAP still keeps this species or not.
For me the most attractive species in Guangzhou Zoo are serpent Eagle, peacock-pheasant, Hainan Eld's deer, Javan rusa, Large&Small Indian Civet, Asiatic Golden Cat, lion-tailed macaque. Maybe you will also be interested in some other Chinese or South-easten Asian species that we considered to be common, such as snub-nosed monkey and South China Tiger.
As for Chimelong Safari Park, it also has many wonderful species such as Borneo elephant, just go and enjor.
