What is the basic governance structure in Hong Kong, Taiwan, “overseas” Chinese, and Singapore?

What will be an ideal response?

• The former British colony of Hong Kong has returned to Chinese rule, but has a government that is somewhat separate from that of the rest of mainland China.
• Taiwan has recently established a multi-party democracy.
• "Chinese in most other countries are typically political minority groups with little political say . . ."
• The city-state of Singapore with a Chinese majority population is a democracy in theory but actually has an authoritarian government run by the same party (often even the same few families)
