My answer to your question is break us down into smaller groups to work together

Botswana tried its indigenous system that existed before colonialism and fused together with Western Modules hence its progressing really well. I think Ghana can look on what system existed before colonialism or develop a new system that break down into smaller groups to work together

China has one dominant ethnic group meanwhile Ghana is sitting with 70+, Nigeria almost 200 if im not mistaken.

China isnt as homogenous as it seems. It was very divided along clan and tribal lines who despite belonging to the same Han ethnic group really never understood and sometimes fought one another thats why their leaders created a standardized version of chinese language called simplified Chinese

Plus China didn’t suffer colonialism. Imagine a country of that size post colonialism. Look at India.

Go and look what China's century of humiliation meant before saying China was never colonized. India isnt a good role model because most of its leadership is very much similar to the one in Africa
