Ochurdyap Mangdaev

Prince Ochurdyap Mangdaev (, ) was the Zaisan of the Second Chui Volost. He took an active part in problematic issues of land management, while preserving the territory of the original residence of the indigenous population. Under his rule, Kosh-Agach became the center of trade routes in the Altai Mountains.

Buddhism Ochurdyap studied medicine with Mongolian lamas, and he also studied Buddhist ethics. In 1885, Ochurdyap created a yurt-shrine, where a prayer service was held on June 12 in the concelebration of six lamas. After the prayer service, horse races with prizes were held.

Kara-Kebeks During the "Uprising of 60 Heroes" many Tuvan families were ruined. Some of the families fled to Altai, namely to the limits of the Second Chui Volost.
