I will translate this paragraph:
The Mang /maːŋ/ people (also known as Mảng Ư, Xá Lá Vàng) are an ethnic group residing in northern Vietnam and southern China (Yunnan province).
In Vietnam they are one of the 54 ethnic groups in Vietnam.
Mang belongs to the Northern Mon-Khmer branch of the Mon-Khmer language family in the Austroasiatic language family.
Mang language is quite similar to Vietnamese but in reality is still different.

You can compare them further here:
