Along route 101 at the entrance of Pua town and at the park in Pua town you will see this 2 fighting mountain beetles (Kwang or Xylotrupes gideon) as symbol for Pua district. As once a year at end September there is the famous Hercules Beetle Festival where local people do fighting games between the best & strongest beetles. The festival is aimed at conserving the local tradition, particularly Hercules’s Beetle fighting. During the festival are also shown other local community traditions like silverware production and local woven textile from nearby mountain villages.
Remark : I mention this festival because it is part of all festivals in Nan province. But personally I have never visited this festival as I think it is a kind of animal cruelty.
