It covers territories of the entire Mong La Township, eastern part of Mong Hpayak Township and to the north borders the northern part of Wa State.

The indigenous peoples of this region are Blang, Pyin, Akha, Hani, Lahu and Tai Lue people, etc. while the lingua franca is Mandarin Chinese.

It was established by sent-down youth U Sai Leun (born Lin Mingxian). Since its active involvement into casinos and endangered wild-animal trafficking, it has been an issue for the Chinese government, which closed the {{ill|Port of Daluo|lt=|zh|打洛口岸}} several times. It also sent police cross border to destruct a casino there, under the acknowledgement of Burmese government. This special region is notorious in southwest Yunnan as they send casino advertisement spam SMS to Chinese cellphones. Organized crime used to be common in this region.{{Citation needed|date=June 2019}}

Sai Leun maintained a good relationship with Burmese army (Tatmadaw) as the Tatmadaw units benefit financially from it.
