I want to know the answer to the following question:
Which Chinese suffix means "area, district, region, ward"?
All the background I'm provided with is that "The modern Standard Chinese exonym for the ethnic Tibetan region is Zangqu (Chinese: 藏区; pinyin: Zàngqū), which derives by metonymy from the Tsang region around Shigatse plus the addition of a Chinese suffix, 区 qū, which means "area, district, region, ward".". Is that enough to answer the question?
