stripping out all the bullshit, here is how the two faiths differ in relieving personal suffering.
confucianism: follow the rules, do as your told. it's not about you. suffering what?
buddhism: most of your suffering comes from clinging to made up stories in your head, and from the belief that suffering can be avoided by following rules.
