Cheng Kung Elementary School(成功國小) in Xigang is famed for its butterfly garden(蝴蝶園). The rich butterfly ecology attracts many educational groups from all across Taiwan. The school website has butterfly films that can be viewed, featuring butterfly mating and the full process of emergence. The children’s are always attracted by butterflies in breeding season and they are captivated by the magical emergence of the mature butterflies from their cocoons. The garden has many Nectariferous plants that attract butterflies; these are carefully protected to allow the butterflies to reproduce naturally. Occasionally, butterflies are caught in the wild and released in the garden. The school also has a butterfly specimen hall with about 100 specimens of butterflies and other insects; there are also maps of the distribution of butterflies globally and in Taiwan and butterfly classification charts on display. The Butterfly Garden is ideal for viewing butterflies and for outdoor teaching.
