involved in Taiwan

Taipei Times - archives: "Wang Xiulian, a Chinese woman who married a man from Taiwan and has been living here for eight years, hates going to the market to buy vegetables.

Some vegetable sellers, knowing she is from China, often ask her: “Do you want to buy 'dalumei'?”

Dalumei means “mainland sister,” a pejorative term for Chinese brides, but also a moniker for a kind of lettuce.

“They do that on purpose. So I turn around and walk to another vegetable stand,” Wang said."
