"这双皮鞋打折。"

Translation: This pair of leather shoes is on sale.

[StevenE.Le]

Could any native English speaker explain to me why "These leather shoes are on sale." is not accepted?

[Ann55075]

...while "These leather shoes are discounted" is

I have the same question

[BryGuy2000]

And in fact, a previous question uses "discounted" for 打折, so there's no reason not to accept both.

[hippietrail]

No English reason. If this is still the case it's a fault in the course.

[Winston298006]

皮鞋 is used as an individual word in Chinese, unlike the less common phrase "leather shoes" in English, though that's the literal translation. 皮鞋 are often dress shoes.

[RohanSoni8]

[woa7dSD5]

Sale by itself is the noun form of sell, but to be on sale means being offered at a discount.

[Jacques439990]

Discounted means "on sale.... This is yet another Birdie blunder..

[Hsn626796]

Where did 字 go after 鞋 ?

[kuyaC]

I got the same question, it's 子 btw.

[Gabrielle145359]

I think "皮鞋” is its own word.
