I'd beg to differ - women still have to go through the exact same system to check off the exact same boxes in order to rise on top of the country. Instead of looking at how many females are on the Politburo/Central Committee, I'd recommend you dig deeper look into their respective careers and see how they managed to make it into the highest levels.
Remember the crackdown on private tutoring not so long ago? If you looked into it a little closer (especially reading up on Chinese sources) you'll learn that the Standing Committee assigned the task to Vice Premier Sun Chunlan. Sun was Party Secretary of Fujian, and during her tenure managed to develop deep connections with neighboring Taiwan enterprises, whilst also gaining experience in commerce and managing macroeconomic projects. Sun displayed enough competency in Fujian that the Party trusted her to head up Tianjin, which at the time was the country's richest municipality. Her previous experience working with trade unions as well as her familiarity working with parties (be it business or political) across the Taiwan Strait made her an ideal candidate to head up the United Front, a major organ of the Party. It was a combination of experience, competency, and achievements that got Sun promoted to the Politburo. Her current management portfolio as Vice Premier spans education and healthcare. Now healthcare plays a crucial aspect in Xi's poverty alleviation reforms, and she's also played a leading role in directing the country's pandemic relief. If the country's education or healthcare system were to be mismanaged, well it will 110% cripple and ruin the country. The Party therefore cannot just assign healthcare and education to their "token female Politburo member" unless she's actually proven she can perform. Lo and behold the crackdown on private tutoring as well as the handling of the pandemic (especially in the initial Wuhan outbreak) is proof of that. Sun's achievements weren't discounted or disregarded at all based on her gender.
Looking forward Shen Yiqin, the current Party Secretary of Guizhou, will almost certainly be promoted into the Politburo next year either to lead one of the Party's organs (probably propaganda, organization, or supervision) or as Vice Premier.... which goes on to show how versatile Shen's skill set and experience is (most politicians track towards the Party or the State Council, you don't really come across party members that can track into both). Although Shen has spent her whole political career in Guizhou, she's played a crucial role in developing the province into one of the country's major tech hub and financial centers. Guiyang wouldn't be such a massive hub for big data and machine learning if it weren't for Shen Yiqin's leadership. Her competencies and achievements have been recognized by the very fact that she's been promoted from researcher, professor, various municipality/provincial party organs, Vice Governor.... all the way till she's head of the whole province.... Might I also add that she was swiftly promoted in her last couple jobs, which goes to show how impressed the Party has been with Shen, and more importantly they are grooming her for the national stage.
I'm no feminist, but I do agree that the party leadership generally does lack in female representation. However the CPC will never just promote anyone because they think the person might have what it takes, but rather they need to see actual evidence of competency regardless of gender or upbringing. The Party can't just increase female representation at the top of the country's decision making bodies overnight just for the sake of #feminism either... Not when 1.4 billion Chinese lives, and inadvertently the global financial and geopolitical sphere, are at stake. However with changing times/norms where there are increasingly more opportunities for women to work their way up the political/social ladder, we need to give it time before women "catch up" with the system and display/develop the same achievements/competencies as their male colleagues in order to be promoted up the chain. The country (alongside the Party and Chinese Confusion culture) doesn't just produce a different calibre of woman, it creates a much more seasoned policy/decision maker than the West. Unlike America where Alexandria Ocasio-Cortez can go from bartender to Congresswoman overnight, CPC party members need to grind out the system over decades before they're even considered for national politics.... regardless if they are a dude or a dudette. The current "problem" is that the pool of eligible candidates that happen to be female is just too small, but I firmly believe that steps have already been taken and the"problem" will be addressed within the coming years. A little food for thought - the Chinese political system is only just working through politicians that grew up during the Cultural Revolution, so I imagine it'll be a while before we see the kind of "influx" of female politicians that the West comes to expect in the 21st century.
