Chinese Locative & Position Words — 方位词 上/下/里/外/前/后/旁边

Locative words (方位词 fāngwèicí) tell where something is. In Chinese, they attach to the END of a noun to form a location: 桌子上 (on the table), 家里 (at home), 门外 (outside the door), 学校旁边 (next to the school). The core words are 上 (on/above), 下 (under/below), 里 (in), 外 (out), 前 (front), 后 (back), plus 旁边 (beside), 对面 (opposite), 中间 (in the middle), and the compass 东/南/西/北 (east/south/west/north).

A key rule: single-syllable position words like 上, 里, and 外 almost never stand alone — they must follow a noun. You say 书在桌子上 (the book is on the table), not 书在桌. The disyllabic forms 上面/下面/里面/外面/前面/后面, however, can stand alone: 里面有人 (there is someone inside).

These words are everywhere from HSK 1 onward, so getting them right early is essential for describing where things and people are.

上 means "on" or "above": 桌子上 (on the table), 墙上 (on the wall), 楼上 (upstairs), 书上 (in the book — written content sits "on" it). 下 means "under" or "below": 书下 (under the book), 楼下 (downstairs), 桌子下 (under the table).

上 and 下 also carry extended meanings. 上 can mean "on a medium": 网上 (online, "on the web"), 身上 (on the body), 电视上 (on TV), 手机上 (on the phone). 下 can mean "under a condition": 在这种情况下 (in this situation).

Note the pair 楼上/楼下 (upstairs/downstairs) is idiomatic — you cannot say 楼里 for the same meaning, because that would imply "inside the building" rather than a floor level.

里 means "in/inside": 家里 (at home), 教室里 (in the classroom), 书包里 (in the schoolbag), 心里 (in the heart/mind). 外 means "out/outside": 门外 (outside the door), 窗外 (outside the window), 国外 (abroad, "outside the country"), 外国 (foreign country).

里 vs 内: both mean "inside", but 里 is everyday and 内 is more formal or part of fixed compounds. Compare 家里 (at home, spoken) with 国内 (domestic, within the country), 室内 (indoor), 校内 (on campus). Use 里 in ordinary speech; reserve 内 for set phrases and formal contexts.

国外/外国 is a useful contrast with 国内/中国: 我在国外工作 (I work abroad) vs 我在国内工作 (I work within the country).

前 and 后 describe physical position: 门前 (in front of the door), 房子后 (behind the house), 车前 (in front of the car). They also express time: 三天前 (three days ago), 三天后 (three days later), 饭前 (before the meal), 饭后 (after the meal).

以后 (afterward) and 以前 (before) are disyllabic forms that often follow a time word or clause: 下课以后 (after class), 来中国以前 (before coming to China). 前面/后面 describe space: 前面有一棵树 (there is a tree in front).

Pay attention to word order: Chinese puts the time word BEFORE 前/后 (三天前 = "three days before"), which is the reverse of the English "before three days".

旁边 (pángbiān) means "beside/next to": 学校旁边 (next to the school), 我旁边 (beside me), 车站旁边 (next to the station). 对面 (duìmiàn) means "opposite/across from": 银行对面 (opposite the bank), 我家的对面 (across from my home).

中间 (zhōngjiān) means "in the middle/between": 中间位置 (the middle position), 桌子中间 (in the middle of the table), 两栋楼中间 (between the two buildings).

These three are disyllabic and can stand alone or follow a noun: 在旁边 (beside it), 在对面 (across the street), 在中间 (in the middle). They are extremely common for giving directions and describing positions.

东 (east), 南 (south), 西 (west), 北 (north) form compass expressions with 边 or 面: 东边/东面 (east side), 西边/西面 (west side), 南边/南面 (south side), 北边/北面 (north side).

They describe relative position and city geography: 学校在城市的北边 (the school is in the north of the city), 中国在北边 (China is in the north), 东边是海 (the sea is to the east).

Combined forms like 东北 (northeast) and 西南 (southwest) name regions: 东北人 (a person from the Northeast), 中国西南 (southwest China). The order is always east/west before north/south, never the reverse.

The verb 在 (to be at) plus a location answers "where": 书在桌子上 (the book is on the table), 他在家 (he is at home), 我在学校 (I am at school), 银行在对面 (the bank is across the street).

When the location is a place name, no position word is needed: 我在北京 (I am in Beijing), 他在中国 (he is in China). But with ordinary objects you must add a position word: 书在桌子上, not 书在桌子.

The pattern is flexible: subject + 在 + location. To say "something is located somewhere", use the same 在 — 医院在学校旁边 (the hospital is next to the school).

Do not drop the position word after an ordinary noun. 书在桌子 is wrong — you need 书在桌子上 (on the table) or 书在桌子下 (under the table). Only place names and a few fixed nouns can omit it.

Choose the right word: 上 means "on top of" (书在桌子上), while 里 means "inside" (书在书包里). Do not mix them up — 书在桌子里 is wrong unless the table has a drawer.

Do not confuse static position words with directional complements. 方位词 describe where something IS (他在楼上 — he is upstairs); directional complements (趋向补语) describe the DIRECTION of motion with 来/去 (他上楼来 — he comes upstairs). They answer different questions.

Remember 前/后 word order for time: it is 三天前 (three days ago), not 前三 days. Time and place expressions always put the measure before 前/后.
