The Sizang, Siyin or Taute people are primarily the descendants of Pu Thuantak, also known as Suantak in the Tedim language and by related clans, and their adopted sons and daughters.
The Zo lived in Zaangpitam until their population increased, forcing them to find more fertile soil, and they dispersed throughout the mountains and valleys in and around Chin State.
In 2019, the Sizang population was about 10,000 in Myanmar and more than 5000 migrated to USA, Australia, Canada, UK, Denmark, Sweden, Japan, Malaysia, India etc.
Si means "salt water", and zang is a northern side or plain; the Sizang originated north of a brine spring.
[2] During the late 19th century, when the British Imperial Army tried to colonise the Chin Hills, the Sizang resisted.
Other Sizang work in the public sector as civil servants, and many have also served as soldiers during World War 2, and also in the Burmese military.
