## Toponymy

The Chinese name for the banner siziwang, literally "four princes", derives from the area's historic rule by four brothers. The Mongolian name for the banner dorbed means "of four".

## History

The area of Dorbod Banner was ruled by four Mongol brothers, Sengge (Сэнгэ, Chinese: 僧格), Suonuobu (Chinese: 索諾布), Bonpo (Бумба, Chinese: 鄂木布) and Yi'erzhamu (Chinese: 伊爾扎木), who were descendants of Hasar, a brother of Genghis Khan. They led their tribe in participating in the Manchu Qing Dynasty's conquest of Ming China in the early 17th century. In recognition of their service, the Qing court made Emubu the Duoluo Commandery Prince (Chinese: 多羅郡王) in 1649 and settled their tribe in the area of modern Siziwang Banner. The title was hereditary and passed through fourteen of his descendants before the Chinese Communist Party abolished all hereditary titles in Inner Mongolia in 1949. The last prince, Sudanamuchaogeji (Chinese: 蘇達那木朝格吉), died as a private citizen in 1957. There is a sculpture of the four original princes in Wulanhua, erected in 2003.

## Spacecraft landing site

The banner served as the landing sites for China's Shenzhou program.
A pasture known as Amugulang, located in Honggor Sum, about 60 km (37 mi) north of Wulanhua, served as the landing site for the Shenzhou-6 spacecraft. A specially constructed 64.69 km (40.20 mi) road runs from Wulanhua to Honggor to aid the recovery of the Shenzhou spacecraft, and to boost the local economy. This road shortened the journey between the two towns from two hours to just 40 minutes.
Chinese space program recovery teams (with SUV and recovery trucks) track the progress of re-entry near the landing site and arrive shortly after landing.
A small recovery trucks fitted with a crane lifts the capsule and places it on the rear of the truck for transportation back to the space centre.
Since the final landing of Shenzhou 11 in Dorbod Banner in 2016, new facilities have been built to hasten the retrieval process for various spacecraft.
In December 2020, the Chang'e 5 spacecraft landed in Dorbod Banner following a successful collection of Moon rocks.
