Hong Kong's terrain is mostly mountainous, and despite the shortage of housing, many poor people live in subdivided units and cage homes, there is actually a large amount of vacant wasteland that cannot be developed due to various reasons. The government can only turn these wastelands into country parks for public enjoyment. Many newspapers have touted these as Hong Kong's "backyards."
However, because they are rarely visited by the public, these country parks have also become perfect spots for dumping bodies. Killers dismember their victims and leave them in the wilderness. Some energetic young men and women go to the country parks for barbecues and outdoor picnics, sharing hormones, and occasionally, someone hits the jackpot by becoming the first to discover a corpse.
Just like Li Yan and Cha Xiaodao now.
