The House of Tsayfenov (Russian: Цайфенов) or the Sainna-hala (Manchu: Саинна-хала) is a Manchu and Aisin Gioro princely family in Russia, who are descendants of Prince Zaifeng, who was the father of the infamous Emperor Puyi.
Unlike the Nikolayevs, the Tsayfenovs are the closest to direct descendants of Puyi, the last Qing Emperor, therefore bloodline-wise, they are the heirs to the defunct Qing Dynasty.
There are several "patriarchs". According to Russian law, Prince Zaifeng is now considered the original patriarch. The first "patriarch" of the House of Tsayfenov is Jin Youzhi, who couldn't resist Vladimir the Tumultuous' attempts to restore the Qing Dynasty to power, as one of Russia's local nobilities. He would join Puzhong (or Prince Nicholas I Tsaytsenovich, son of Prince Zaishen/Tsayten), but however, he was alarmed when the Russians charmed their way via Russification, baptizing him as Russian Orthodox - Jin Youzhi became Prince Vladimir I Tsayfenovich, hence the original namesake of the Vladimirovs, teaching them Russian lifestyles and ways without much regard for native Manchu culture.
While Nicholas I Tsaytsenovich would go on to rule Russian Manchuria as the first Aisin Gioro prince, let alone Manchu, despite being addressed as Prince Vladimir of Manchuria, he quickly found out that neither the Russians or the Chinese had good plans for the Aisin Gioro, and rebelled against the Russians, without much of a goal. He died in battle against both Russian and Chinese forces.
The Russians however, continued to help Jin Youzhi's son, Jin Yuzhang (baptized as Prince Joseph I Vladimirovich), become a Russian statementsman for the Tsar, however. At this point, because Emperor Puyi was an enemy emperor, and Prince Vladimir was a traitor, the royal house's name was changed to the House of Tsayfenov, after Prince Zaifeng. However, the prominence of the Nikolayevs had pretty much overshadowed that of the Vladimirovs, in which the Nikolayevs would carry on the Qing Emperor title, with much controversy from both Russian and Chinese authorities.
