No posthumous title. Prince Yi is * * * seven generations and nine kings. Four of them are posthumous title-free, one is Zafang who was attacked for the fourth time, Zai Yuan who was attacked for the fifth time, and the other two are sons of Putin who was attacked for the eighth time and Yu Qi who was attacked for the ninth time.

Putin didn't have posthumous title for another reason, because he was knighted after his death, so there was no posthumous title.

During the Boxer Rebellion in the 26th year of Guangxu (1900), Duan Wang initiated the theory of "suppressing foreign countries", and Prince Yi, Zhuang Zaixun, Fuguo Gong in Lan, Baylor in Lian, Britain and Beizi Pulun all responded (see Duan Wang Zaiyi for details). After Eight-Nation Alliance entered the city, Putin was honored as a prince, but he died because of the humiliation of German soldiers. After his death, he was demoted by the Qing court on the charge of "protecting boxing bandits and making troubles".
