..i was in Rejoi and Sait last year and communicate with them in Biatah B

The Tringgus has a long relationship with the Biemban (the Semban and Rejoi people), stories of war, migration, etc. They speak more or less the same dialect because of their origin and their common history. I've been told that there is still the jungle path that the Rejoi and Tringgus people used to tread on hundred of years ago and this path still exists along one of the passes in the Bengoh range. It would take around 6-8 hours walk, according to them lah...

Sait and Bojong group belong to the Bitebia' dialect, which consists of settlements in Maras, Kiding, Jabir, etc.

As for the Sadir/Simuti groups, they belong to the bigger Biannah (Benah) group of Annah Semeru, Annah Rais, Annah Sadir, Annah Simuti, Annah Sibuang and Annah Sibukar. I was told by people in Simuti that they originally started in Rais before settling in Simuti. Then, slowly they spread out to Sadir, Sibuang and Sibukar. As for the "Tebedu side", actually, some families moved to that area many years ago. I can't remember the time but it's in my notebook somewhere. The place on the "Tebedu side" is called Tepoi, and they speak more or less like the Biannah.

thanks lfiction for very usefull info......

...when i was at SImuti a guy show me a general direction where Tepoi is (just a mountain range for me...heheee)....and also where Tebedu is..and view from that place there is awesome....

..he also show me a walking trail (jalan tikus) which will lead to a bidayuh kampong in indon side...

and i believe all of this will need a proper documentation...

Tepoi is just about 2 hours walk from Simuti. There's only one steep hill to climb and for the rest of the time, you'd be walking on the mountain ridge. I must agree with you, the scenery is beautiful especially in the evening. I would go to Simuti just to watch the sun goes down beyond the mountain ranges.

As for the Bidayuh kampung in the Indon side, I've been to Siding and also Sebujit from Gumbang (can also walk from Tringgus, about 7-8 hours). From Sadir, it's about 3-4 hours' walk to the next kampung on the Indon side called Ba'Giam in Kepala Pasang.

Documentation? Even if you bring your passport with you to these places on the Indon side, who will stamp it for you? You may only need to inform the Indonesian soldiers at Siding if you're going to Sebujit or Botok. But for Ba'Giam side, there's no checkpoint.

yeah Lfiction...the scene is awesome...do you have any picture to show?....
i have a few from my last trip...share later....

...thats true as what my fren said...walk for 3 4 hours and reach the bidayuh community on the other side..and you're able to trade with them almost any exotic fauna and flora...

I've posted some of the photos into my blog and most others into my so-called 'pictorial' blog. This one is taken from that staircase shed in Simuti sometimes last year. Time was around 7pm.
