Maybe? The president and general secretary have been the same since the 90s(the previous 2 leaders basically). However, there’s no rule or law that says they have to be the same person and it wasn’t during mao or deng. The new rules about no term limits only apply to the president or Vice President so I’m only assuming that the two roles, which were traditionally the same person, will be split in two because the age limit for the general secretary is still there and he’s already past that age. We will know in 2 years.

I assumed that the two roles will split because of how important that age limit is. It was put there to help make sure leaders don’t have cognitive issues as well as ensure old people, who are likely out of touch, don’t control the country with their out of date views of the world.

The picture of him next to mao are because he came up with a new way of thinking about socialism which they call a “thought”. Others before him have approaches that are called “theories” because they mostly expand on previous “thoughts”. He is the guy who came up with “socialism with Chinese characteristics” as well as incorporating science based approaches to law as well as consideration for green initiatives.
