In this week we are actively conducting several searches for the historical sites of the Sumatran heritage. My friends and I went into the interior, which we thought were some old villages that had intact historical value. The first day we found some of the Sumatran royal heritage coins made of silver, as well as one small box that we thought was a coin storage area. About 20 kilometers into the forest, we also found several ancient tombstones, which were around 600 years old. Based on the similar motives of the previous findings, we can be sure that it was the tombstone of the settlement of the Sumatran people, in their time.
