Which of the three systems of chinese ethnics would be the best way to rule a country

The Han people are the largest ethnic group, where (as of 2010) some 91.51% of the population was classified as Han Chinese (~1.2 billion). Besides the Han majority, 55 other ethnic groups are recognised in China by the PRC government, numbering approximately 105 million people, mostly concentrated in the northwest, north, northeast, south, and southwest but with some in central interior areas.
