While talking about probability with mainland Chinese students I asked what they say for heads and tails of a Chinese coin. I was tossing a one Yuan coin, and they decided I could say in English "flower" and "number".

I did not want to go on talking about language so I did not ask what they actually say in Chinese. But when I search on line I do not find anything like this. I mostly found 正面 and 反面, which are also what Google Translate offers.

I wonder if 正面 and 反面 are just the technically correct terms, like "obverse" and "reverse" in English, which most people never say.

Are there more common mainland expressions for the sides of a coin?

  • 正面 and 反面 are OK.

    In Cantonese, "Head" is "公" (as in 公仔= figure) and "tails" is "字" (writing).

  • Yes, before the students settled on "number" for tails, some had suggested "character." These are Beijing students. Commented May 29, 2018 at 2:20

Chinese use 正反 more than US people use obverse/reverse.

Other words are 花/字, but the side is controversial.

The side of 中华人民共和国 is 正面, but many many people think 1元 is 正面, this would be more confused if you use 字/花. Which side is 字, is it 正面? enter image description here

China bank realized this problem, the new coin:

Now 中国人民银行and 1 元 are on the same side, that is 正面, in this case 字 is 正面, 花 is 反面.

In some dialect, people use 字/背.


正面 and 反面 is the technical term for it I think.

Colloquially, we use 字(the side with number) and 面(the side with head). In northeast, it's been erhua and it becomes 字儿 and 面儿. The interesting part is 面儿 is pronounced as mer4, but mianr4 is also correct I think.

    I live in northeast, I almost forgot that, old people call 面 as "闷儿".

According to this Wiki entry, 正面 and 反面 is what Chinese call "head and tails" of a coin.

正面 of a coin is the one side with a figure head, and the side without a figure head is 反面

(For old Chinese coin, the 正面 is the one side with engraving, and 反面 had nothing on it)

In Cantonese, "Head" is "公" (as in 公仔= figure) and "tails" is "字" (writing).

  • Yes I am sure coin experts in China call the two sides of the coin 正面 and 反面. The US Wikipedia says that in English the sides are usually called "obverse, and reverse." But that is only true when you speak about coin experts in the US. Ordinary US people do not know the term "obverse." Ordinary US people always call the two sides "heads and tails." Maybe also in Beijing ordinary people call the "tails" "字." I will see the students again this evening and ask some of them before class begins. Commented May 29, 2018 at 2:38
