Partly disagree. For 前面/後面 vs. 前邊/後邊, both 《现代汉语词典》(5th ed.) and 《中華民國教育部重編國語辭典修訂本》 consider 前面/後面 respectively **equal** to 前邊/後邊; and I don't see much difference between them in daily use. For 外面/裡面 vs. 外邊/裡邊, setting aside the special meaning of 外邊, they are also considered the same by the two dictionaries. For 左面/右面, I agree with the case 墙的左面, but it's a special case that 左面 here means the "left face" but not "on the left side".

@Stan, based on my own experience, I have never heard anyone say 镜子前边. Neither have I heard of 书包里边. As such, I disagree that they are equal regardless of what is prescribed in 《现代汉语词典》. Although there are cases where the usage of 面 overlap with 边, we should learn to distinguish them for the sake of clarity.

The problem is, both 镜子前边 and 书包里边 sound valid to me, and I did have heard it (and even occasionally I would use it :p) user58955's comment in OP's post said `it's a regional thing... Northerns use 边 more and southerns 面`, I think it is quite possible (as I've stayed in northern China for several years), though I didn't see any statistical analysis for this issue.

There seemed to be some misunderstanding ... I totally agreed with your explanations of the single characters 面 and 边. My point was 前面 is not exactly equal to 前+面, and 前边 is not exactly equal to 前+边 either. Hmm, in exact match via Google, "镜子前边" vs. "镜子前面" hit 49,900 vs. 585,000 here, not bad for the previous one. Well you would say many Chinese people use it in a wrong way, but I think the inference like `前+面 => 前面` doesn't have to be always correct either.

<p>as a native speaker, i would almost always use 前面，後面，上面，下面，裡面，外面, but 左邊 and 右邊 for simple positioning. no why, they just sound right to my taiwanese ears and i guess you can use 邊 for all of them and it would sound more mainland-ish. even more general is 旁邊 (next to), which has no discernible direction. e.g. 我坐在他旁邊, 超市在加油站旁邊</p>

<p>as a side note, for 前後左右上下 ＋ 面/邊, there's no concept of inside or outside, so something like 火車前面 can mean both "at the front of the train (inside)" or "in front of the train (outside and about to be hit!)". in practice it never really causes too much confusion because you can tell from context. e.g. 駕駛座在火車前面 or 有東西擋在火車前面。</p>

Confusion about bian 邊 and miàn 面
# Confusion about bian 邊 and miàn 面

(Asked by: username_0 on 2014-02-16)

I'm having a little trouble with learning directions and positions. It seems that most often the word bian is being used to indicate a position: front side 前邊, back side 後邊, etc.

But then I see stuff that uses mian for position: 外面有人吗?

So I'm a little confused as to when I should use bian and when I should use mian. Can you help me come to an understanding of the two?

To understand the differences properly, you need to know what is 面 and what is 边. 面 is a **face** whereas 边 is an **edge**. An edge is like a line guiding you the *direction*. A face is what is facing you giving you a sense of *position*.
