Bingbing, who appeared in the 2014 blockbuster X-Men: Days of Future Past, recently scored zero out of 100 when ranked in a Social Responsibility Report compiled by the government and she is also thought to be in the middle of a tax evasion investigation.
The actress topped Forbes magazine's 2017 list of top-earning Chinese celebrities with income of 300 million yuan (43,687,500.00 USA dollars).
Meanwhile, a watchdog site covering social media censorship in China notes that concerned supporters who wondered online what had happened to Fan have since seen their posts scrubbed. However, last week, state-run publication Securities Daily reported that Bingbing has been placed "under control". It is speculated that she is caught up in an investigation over the "yin-yang" contracts which breach the honest report of the actor's real salary as opposed to the small figure that they submit to the tax authorities.
Other news outlets have for months speculated on Fan's whereabouts, and rumours circulated that she was living under house arrest, according to The Epoch Times, a USA newspaper focusing on China.
Fans became concerned when Fan Bingbing, one of the world's highest paid actors, stopped posting on social media in July. The actress, who has been repeatedly listed by Forbes as China's highest-paying actress in the past few years, was also accused of several other crimes, including illegal bank lending and other corrupt practices.
The 2017-2018 China Film and Television Star Social Responsibility Report ranked stars based on three main criteria - their film and television work, their charitable activities and their behaviour. Fan has done so much good work in the past!' One user wrote on the Twitter-like Weibo platform.
Her disappearance came after Cui Yongyuan, a former TV host with the state-owned China Central Television, suggested that the actress had signed secret contracts with a Chinese entertainment company to avoid paying taxes.
The 36-year-old actress has vanished from public view after she became embroiled in June in a scandal about movie stars under-reporting their earnings.
Her studio denied any wrongdoing from her side.

As her disappearance has dragged on in recent weeks, more rumors have surfaced that Fan is facing an acting ban - or even house arrest.
Last month, almost a dozen major Chinese film producers and video sites announced they also would boycott "unreasonable" pay for actors.
Fan Bingbing may have been detained by authorities.
Bingbing had been cast in upcoming all-female spy thriller "355" but it's not known if she will be available for filming given her current circumstances.
