Once upon a time, there lived a beautiful woman named Dayang Sumbi.
She lived deep in the forest with her dog named Si Tumang and his son named Sangkuriang.
One day, Dayang Sumbi asked Sangkuriang to hunt a deer with Tumang.
However, Sangkuriang did not manage to get one, so he decided to kill Tumang and bring his heart to his mother.
Dayang Sumbi, who knew about it, was angry and kicked Sangkuriang out of the house.
Several years later, Sangkuriang accidentally met Dayang Sumbi and fell in love, not knowing that she was his mother.
Dayang Sumbi, who knew that the man was her son, refused Sangkuriang’s proposal.
She then asked a very tough conditions, which were to dam the Citarum river and build a big boat in the middle of the dam.
Because it did not finish on time, Sangkuriang got angry and kicked the boat and it became Mount Tangkuban Prau.
