I'm not an expert on the gender dynamics of the political system, so it's something I'll have to look into, but to address the term limits thing, I kinda have to explain how the political system of the PRC works.
The way the President of China is decided is on the system of the People's Congress. Starting from the lowest, most local level (will refer to as level 1), grassroots civilians will elect a congress representing the village/town. Larger populations elect people to a congress representing whole smaller cities, municipal districts or a county. This is level 2. Then for level 3, it's a congress for cities and prefectures. Level 4 is a congress for provinces and autonomous regions. Level 5 is the National People's Congress.
Depending on where you live and how populated, as a grassroots/civilian voter level, you elect someone to level 1 (more rural areas) or 2 (cities). Then, candidates from 1 & 2 elect someone among them to move up to level 3, level 3 select someone among them to move up to level 4, and so on. Its not possible to "skip" levels, you can't get elected into a position of power unless you've held a lesser position of power and was competent enough for your equals deem you worthy of advancing. Level 5, the National People's Congress consisting of around 3000 delegates, then elects the Central Committee for the PRC as well as the President of China by majority vote. The move to abolish term limits was put forth and passed by the National People's Congress. They must have thought it was inconsequential, or it was more important to consolidate power during rising tensions with the west. Whatever the reason, this did not increase the powers of the office of President. If it was a malicious power grab by Xi, this was a poorly done one since General Secretary (the leader of the executive branch of government) had no term limits to begin with and holds more power (for reference, Deng Xiaoping was never President, but served 3 terms as General Secretary but was the most influential man in China during his active years)
Now, term limits in and of themselves aren't necessarily good or bad. They were never in the original constitution of the PRC to begin with, were added I believe in the 80's and abolished in 2018 since its effectiveness is questionable. German Chancellor's have no term limits, nor most countries with Prime Ministers.
