A photo from the campus shop:
I transcribe and translate this to:
Purejoy promotion: 7 yuan/bottle
(Here, Purejoy (纯享 chúnxiǎng) is a brand of yogurt.)
Question: Why is ７元/并 written instead of ７元/瓶?
- 并 is an abbreviation for 瓶 (which I think is the most likely case).
- It's just incorrect.
- A unit of this product is called a "并", which I haven't heard of before.
