Zow Tlang or Reang Haphong is a peak in the Mowdok range located at on the border with Myanmar. Its peak is at an altitude of . According to Bangla Trek, it is the second-highest peak in the country, though it has not yet been officially recognized by Bangladesh's government.
The local name comes from the Bawm language. The name 'Zow' refers to 'Mizo', a derivative of Mizoram in India. 'Tlang' means mountain in the Bwam language. The official name, 'Mowdok Mual', comes from American and Russian topographic maps.
A few months after this expedition, a team of Bangladeshi travelers led by Zaqiul Deep measured the height at 3,312 ft. (1,009 m). A third team also reached the summit later led by Fahim Hasan of BD Explorer. There is no doubt about the height of Dumlong but whether it is the second or third highest mountain in the country is yet to be confirmed. Nevertheless, it is indeed the highest peak of Rangamati Hill District and one of only three mountains measured at more than a thousand metres in height.
In 2014, several teams climbed the summit of Zow Tlang, and based on their readings, they surmised Dumlong is the third-highest mountain in Bangladesh.
