The German president can only be elected two times and he has limited power. The German chancellor also has limited power. Terms for chancellor are not limited, but he/she has to be elected every 4 years. Merkel barely made it this time, and it's almost certain she will not be re-elected next time and also very likely that she will not strife for candidacy next time. Comparing China's system with Germany's makes a lot of sense, but you have to do it correctly. If Xi would be a chancellor with limited power in a parliament that consists of members of 6 different parties, then it would be less of a problem if he ran as a candidate in a third election.
