One expert tracker, Wang Min-nan, an officer with the Panchiao police, points out that in comparison with cases of lost elderly people or unidentified corpses, it is much more difficult to find individuals who have voluntarily left home. Since these cases involve relatively "mobile" people who have no fixed residence, they are usually found when police make inspections at places like Internet cafes, pool halls, or KTV parlors.
尋人高手之一──板橋分局警員王閔南指出，相較於走失的老人家或者無名屍體比對，逃家青少年等自願性離家者因為居無定所、「移動性」較大，尋獲的難度較高，一般多在員警臨檢網咖、撞球場、KTV 等場所時被查獲。
