Both 部 bù and 邊 biān边 biān go after direction words like 北 běi (north) or 東 dōng东 dōng (east), but they mean different things. 部 bù is a part or region inside a place (“the northern part of Taiwan”), while 邊 biān边 biān is a side or direction, often outside or next to something (“north of Taiwan,” “on the left”).
一 部 · A Region Inside
Place + (的) + direction + 部
部 bù refers to a whole region within a country, city, or area. It sounds a bit more formal and is common in the news and weather reports. It only works with the compass directions.
Canada is to the north of the US, and Mexico is to the south.

邊边 or 面?邊 biān边 biān can also be 面 miàn: 前面, 後面后面, 右面. In Taiwan, people usually say 前面 qiánmiàn and 後面 hòumiàn后面 hòumiàn for front and back, but 左邊 zuǒbiān左边 zuǒbian and 右邊 yòubiān右边 yòubian for left and right.
三 部 vs. 邊边
The easiest way to remember: 部 bù is inside the place, 邊 biān边 biān is outside or next to it.

四 Common Mistakes
❌ 台北在台灣台湾的北邊北边
✅ 台北在台灣台湾的北部
Taipei is inside Taiwan, so use 部 bù.
❌ 加拿大在美國美国的北部
✅ 加拿大在美國美国的北邊北边
Canada isn’t part of the US. It’s outside, to the north, so use 邊 biān边 biān.
❌ 那棟栋樓楼在右部
✅ 那棟栋樓楼在右邊右边
部 bù only goes with compass directions. Left, right, front, and back always use 邊 biān边 biān.
五 Practice
Try it yourself
