More than ten years ago, the site of Zhenhai Park was only a closed beach. Nobody was allowed to go near and seaside patrols watched this place closely. Only in the religious ceremony held every three years, residents could get close to the sea in the activities such as invitation of water and burning of king boats. Even locals would like to enjoy the seaside, they had to drive 50 kilometres to the south of Fanshan.
Mr. Hong believed that it is necessary to make seas accessible to the public, as Taiwan is an island and marine culture is important. He gathered a team, consisting of mainly directors and supervisors of Jhen Hai Kung Management Committee, and established Donggang Cultural & Environmental Development Committee. The first task was to make the seashore open to the public. This was how Zhenhai Park, the most northern seaside park in Pingtung County, was born. A beach cleaning vehicle, worthy of NT$4 million, was sponsored by the Environmental Protection Administration, for the clearing of garbage on the sand and floating trash on the sea. Directors and supervisors of the committee led a team of volunteer workers to clear off an area of more than 10 hectares, next to sea walls and the seas.
The task of Mr. Hong and the other members of the board did not stop here. Forests were required in order to provide shading areas. The beach was completely barren other than the occasional traces of perennial vines such as seashore vine morning glory. There was no tree at all. Seashore vine morning glory, a member of genus Ipomoea, takes root everywhere and crawls tightly on the ground to fend off gusty winds. However, they were little use to tourists. Mr. Hong asked Forestry Bureau for Casuarinaceae, varigated coral-trees, Taiwan nato trees, karum trees, Diospyros philippensis, Hibiscus tiliaceus, coconuts and cyclamen in order to initiate a trial program of a thousand plants. Survival of plants is difficult in the sandy and salty seaside. It is necessary to water the plants and wash their leaves. Mr. Hong led a team of volunteer workers and continued their efforts in bringing life to the wasteland. Finally, Hibiscus tiliaceus blossomed and Diospyros philippensis fruited on the arid sand land. Before the lush green park came into being, thousand of plants had withered away. Pavilions, landscape stones, pavements, phone booths and public toilets are also the result of hard work.
