Could you explain what you mean by a complex naming convention?

So in China, the emperors sometimes would have temple names (that is, the name you will be addressed in the imperial temples) and posthumous, names meant to address your life's work if you are a ruler. In a vastly simplified description, the temple name suppose to began during the Shang time, where ancestral worship can go only so long, thus only major figures can go to temple, and were given names that have specific meaning. For example, those who founded things are given the name Tai, or beginning. Those that done great things were given name Gao, or high. Those that restore were given Zhong, or center. The Zhou court did not use this, nor the Qin, but the Han court 'restored' it. So you have one naming convention tracing its legitimacy back to Shang.

The Zhou court under Duke Dan set up the posthumous name, meant to be generalization and reflection of that person's reign. It can be a good posthumous name, for example, Wen (or scholarly), meant ability to control heaven and earth, or insane amount of widsom. Or Kang, one who provided stability and peace to his people. There were only good ones or neutral ones at the beginning, until Emperor Li (posthumous name) of Zhou, who happen to be more of a party happy bad ruler, and everyone decided that it was just a bad idea to give him anything neutral. So lets make him the (Zhou) King Li (his name was Ji, Hu), as one who guarded his people's mouth (and their comments of him) more than he guards the flooding (of yellow river). Or (Zhou) King Lin, with luck the nation was not brought to its knees, but where chaos reign and he did nothing. Some neutral ones like min, one who has died while serving his country.

The key difference then would be the philosophical view of where kingly power came from. The Chinese temple names were meant as a final reflection of that emperor's reign. Whereas European monarchs after the Roman empire reign through grace of God, thus questioning their reign would be seen as heresy, the Chinese believed in the mandate of heaven, that while the emperor may be the son of Heaven, but his action can and will influence the divine will, and will send punishment and such. And therefore you can criticize them for their error, and what better ways to give them a nick name that will last thousands of years. （I learn about Zhou King Li's foolishness as a child, some 2700 years after his death, but never learn of his actual name until I had to type this.)
