Gengliao Historic Trail is one of the five historic trails that links Nangang to Shengkeng and Shiding. It is well-preserved and still in use. This trail is not only a shortcut to Shanzhuku and Tukuqiu， but it also leads to some ancient relics. Today， the trail is paved with granite， and despite its renovation， it still has a touch of archaic ambiance.Starting point of Gengliao Historic TrailThe ancient "Pan's Family House" is the only house in Nangang that still possesses bullet holes from war， and is still inhabited. Eight generations of the Pan family have lived here， meaning that the house is at least 160 years old， as old as the trail!On the way to Laoliao Historic Trail， the Shihui Mine Tunnel is a remnant of our forefathers' exploration. The remnant of Wei Jingshi Residence recalls the origin of the once prosperous tea industry here， despite the current sadness reflected by its remaining walls. Other places such as Tujiao House， Zheng's family graveyard and the mere 30cm tall Land Deity Temple are all evidence of the ancient history of this trail.Rediscovering the Home of TeaThe history of tea development can be traced back two hundred years. During the rule of Emperor Qianlong， this place was an important production center of camphor and tea.
