When Li Yuan-hsin, a 36-year-old high school teacher, travels abroad, people often assume she is Chinese.

No, she tells them. She is Taiwanese.

To her, the distinction is important. China may be the land of her ancestors, but Taiwan is where she was born and raised, a home she defines as much by its verdant mountains and bustling night markets as by its robust democracy. In high school, she had planted a little blue flag on her desk to show support for her preferred political candidate; since then, she has voted in every presidential election.
