Difference between 最高领导人 and 主要领导人之一? I've just been looking at the wikipedia entry for Xi Jinping and the word used for the position he will be taken on Wikipedia is incumbent "paramount leader" with paramount leader pointing to this Wikipedia article. There is also a Chinese version of that page which translates paramount leader as 黨和國家最高領導人.

However if I look at Hu Jintao's Chinese page it uses the phrase 中国共产党和中华人民共和国的主要领导人之一. With 主要领导人 pointing to this page 党和国家领导人.

If I look at the very bottom of the 党和国家领导人 it also has 习近平（最高领导人）.

I'm hoping someone can help me, and forgive me if the answer is on the linked pages (my reading is too slow).

Here are my questions:

党和国家领导人 - Is this singular or plural or both?

What is the difference between 最高领导人 and 主要领导人之一?
党和国家领导人 is both. It can refer to a few people or just someone. For example, 党和国家领导人某某(和某某)出席了某个活动。
最高领导人 can be translated as supreme leader. There must be only one at one time. And 主要领导人之一 is just some one important.  For example, only 5 最高领导人 in PRC history. But anyone in the Political Bureau is one of 主要领导人。 


The address(称呼) of important people of CCP is significant and subtle. Similar address may have big difference. Here is a great Chinese post analysing how to call CCP leaders after their passing, the best I've ever read.
