"Harmony" is the harmonization of musical notes, as well as the harmony between heaven and earth. 

The harmony and beauty of the ecosystem are the most precious treasures bestowed upon humanity by nature. In response to global climate change and the protection of beautiful natural landscapes, the Chinese government has put forward the policy of "protecting mountains, rivers, forests, farmlands, lakes, grasslands and sands." 

In response to the rallying call to live in harmony with the natural environment, the HKCO has lined up a programme which recreate the environmental backgrounds of different landscapes.
