For more than a decade, a tacit understanding among Chinas top rulers has ensured the ruling Communist party does not become a gerontocracy. That understanding, known as qishang baxia or seven-up, eight-down, dictates that only leaders 67 or younger can ascend to or remain in top posts, while those 68 or older must retire when the party changes guard every five years.
But as China prepares to enter a selection year under the leadership of a very unconventional president, Xi Jinping, there is increasing speculation he may try to dispense with the retirement convention entirely.
If so, it will be the biggest test yet of his authority over the party and further distinguish him from his predecessors Hu Jintao and Jiang Zemin, who took a first among equals approach during their presidencies.
To waive the rule is going to be difficult because it would establish [Xi] as significantly more than first among equals, says Steve Tsang, a sinologist at Nottingham university.
It would also be the strongest signal to date that Mr Xi could ignore a similar unwritten rule on term limits that would require him to step down from his current position as party leader in 2022.
Mr Xi heads the seven-member Politburo Standing Committee, the partys most powerful body. Since 2012 he has overseen a draconian anti-corruption campaign and asserted his authority over the military and even economic policy, an area traditionally delegated to the premier.
As a result, he is widely regarded as the partys most powerful leader since Deng Xiaoping, the architect of Chinas reform and opening, if not Mao Zedong, the partys revolutionary hero.
Mr Xi and his premier, Li Keqiang, will be 64 and 62 respectively when the 19th Party Congress convenes late next year to appoint a new Politburo Standing Committee and State Council, ensuring both men another five years at the top of Chinas party-state.
All five other members of the Standing Committee will be required to step down under the current retirement rule.
This rule is not enshrined in the party constitution and was only introduced by Mr Jiang in 2002 as a way to ensure one of his rivals could not stay in office after he retired.
Despite its arbitrary origins, the age limit is seen as a strong sign of institutionalised rule that is crucial to the partys claim to legitimacy.
For Mr Xi, the 19th party congress will be an unprecedented opportunity to stack top party and government posts with his allies, giving him even more authority. Just wait for his second term is a common refrain among the presidents supporters, many of whom admit privately that the party has yet to deliver on many of the bold economic reforms promised at the outset of his presidency.
But a year can be even longer in Chinese politics than elsewhere. Jockeying will begin in earnest later this month at an annual gathering of the Central Committee membership of which is a prerequisite to serve on the Politburo Standing Committee and it will continue right up until next years congress.
Xi appears to be strong on the surface, says Qiao Mu, a Beijing-based scholar. But its hard to say if he can get what he wants [at the congress]. Nobody knows for sure until the last moment.
Willy Lam, a China expert at the Chinese University of Hong Kong, says: I dont think anyone is powerful enough to openly challenge Xi if he wants to ignore the retirement rule. But people would definitely fight it internally.
If the qishang baxia rule is waived, party insiders say the immediate beneficiary would be Wang Qishan. Mr Wang has spearheaded Mr Xis anti-corruption campaign and turns 69 next year. Technically the partys sixth-highest-ranking official, Mr Wang is widely regarded as second only to the president in terms of real clout.
Mr Wang, a veteran banker involved in every pivotal financial reform since the mid-1990s, is the most economically literate member of the current Politburo Standing Committee at a time when the Chinese economy faces mounting problems.
After enduring a credibility-sapping series of market and currency crises in the second half of last year and early 2016, economic growth has stabilised with the help of one of historys biggest credit bubbles. Now Mr Xi and Mr Li are attempting to deflate that bubble without denting economic growth.
Wang likes the idea of staying on, says one person close to the party leadership. But he is worried about the precedent it might set for Xi himself.
Mr Xi will be 69 at the expiry of his second term as party general secretary in 2022, and thus ineligible for a third term. But if the retirement rule is waived for Mr Wang, then it could be waived for Mr Xi as well.
In a rare hint that he may indeed be contemplating a third term, an official journal quoted the president in early 2015 as saying that the party cant simply draw the line based on age when appointing officials.

Xi loving it! Going to be interesting to see if he will do it or not. He can go for a 2nd run. But people expect him to get rid of the retrement rule during that term.
