Chan Chan Dare or Chan Chare are called two pieces of stone by local people that join all together in marked symbol and made in small hole. When the passenger arrived there, they always dropped cash coins (ancient coins) into this small hole.When cash coins are dropped in, it makes soft weak voice like a voice of the birds sing or music with happiness.
