Juyong Pass
Dodo died of smallpox in 1649 at the age of 36. Dodo was said to have a very close relationship with his brother Dorgon. Dorgon was attacking Jiang Xiang (姜瓖) in Shanxi when he heard that Dodo was severely ill, so he immediately turned and rushed back to Beijing, but when he arrived at Juyong Pass, he received news that Dodo had died. Dorgon was so grieved that he changed into plain robes and cried as he raced back to Beijing.
