Like China you mean? The People's Republic of China? I guess calling something a "Republic" makes it one, so all we'd have to do is convince Emperor Stephron to call his Imperium a "Republic" and it would automatically be one, I am not that gullible I'm afraid.
No offense, but you appear to be not very informed either.
Neither the PROC or the Russian Federation are dictatorships, as they have no actual dictator as their head officials are elected into power.
Russia is a semi-presidential republic (meaning it has both a President and Prime Minister rather then just one or the otherd) with a multi-party representative democracy as it's fundamental structure.
China is organized under a socialist republic format. It actually has a congress too technically, but their power is fundamentally limited to stamping things the current group of Party officials in power sends their way, so it's mostly a formality at best.
Not saying either are especially great places to live; Russia has economic problems that seemingly won't go away with a governmental authority that is somewhat heavy-handed and conservative when it comes to freedom of speech and China has all the problems apparently inherent in large socialist groups as well as huge internal corruption problems and internal strife stemming from the fact that Tibet, Xianjing (Kazakhstan), and Inner Mongolia would rather not be a part of it at all, as well as the newer political tensions in Hong Kong.
But they are not however, dictatorships, especially in China as Xi Jinping legitimately worries constantly about being removed by the rest of his own party since his corruption crackdowns have pissed off a lot of influential people in his own government.
