BEIJING (AFP) - The mouthpiece of China's ruling Communist Party on Monday carried a rare denunciation of retired leaders' continued influence, fuelling speculation over how far President Xi Jinping's anti-graft campaign could go.
Mr Xi's much-publicised drive against corruption has ensnared a long list of senior and junior officials including the country's former security czar Zhou Yongkang, who was sentenced to life in jail in June.
Zhou is regarded as an ally of former President Jiang Zemin, who ruled from 1989 to 2002 but is believed to have retained significant power throughout the following decade, when Mr Hu Jintao was President.
Speculation has circulated over whether Mr Jiang could be targeted by Mr Xi and the party's internal investigation branch, the Central Commission for Discipline Inspection (CCDI).
In February, the CCDI posted an article online about princely corruption during the Qing dynasty, seen as alluding to Zeng Qinghong, a former vice president and Jiang's right-hand man.
Monday's People's Daily commentary lambasted unnamed "retired leaders" for clinging to power and causing rifts within the party.
"Some leaders not only installed their cronies (in key positions) to create conditions for them to wield influence in future, but also wanted to intervene in the major issues of the organisation they formerly worked for, even many years after they retired," it said.
Such actions made new leaders feel that their "hands and feet" were fettered by having to work within "unnecessary concerns", it added.
They "also has made some organisations... split up into groups and become demoralised... undermining the party's cohesion and capabilities," said the commentary, written by Mr Gu Bochong.
Mr Gu is an officer with the Chinese military's General Political Department, according to the website of the China Writers' Association, of which he is a member.
The People's Daily did not provide of description of Mr Gu, although it did so for all the other contributors to its "Theory" page, which appears every weekday.
The article compared a leader's retirement to the waning temperature of a hot drink.
"The tea must cool after the guest left, otherwise it will go bad," it said. "It should become a norm that when you leave office, you leave your opinions behind."
The metaphor sparked a wave of allusions on China's Twitter-like Sina Weibo.
"What if the ginger tea just wants to stay as hot as before?" asked one poster. "In that case, it has to be poured away!"
In Mandarin Chinese, ginger is pronounced "jiang".
