Chinese cemeteries are often viewed as dark and eerie places and are to be avoided except during the Qing Ming prayers. Chinese immigrants to Malaysia but who did not return to China were buried in cemeteries established by their clansmen. The hundreds of Chinese cemeteries are now part of the Malaysian cultural landscape. Culturally the cemeteries symbolize the core Chinese concept of the "unity of heaven and humans". This concept is manifested through three key cultural values of filial piety, fengshui (geomancy), and yi (righteousness). On the practical level, the management of Chinese cemeteries is nurturing a "green culture" primarily through efforts to "humanize" the cemetery landscape. This objective is being pursued in three ways, namely, changing the image of cemeteries, developing garden-type memorial parks, and increasing the level of human presence.
