Some Chinese words, for "sale"
挥泪 吐血 跳楼价 大甩卖
huī lèi tù xuè(xiě) tiào lóu jià dà shuǎi mài
挥泪
Shed tears, wipe away tears.
挥 is a verb, means wave.
泪 is tears.
吐血
Hematemesis. In short, throw up blood.
If you are wondering what the hell a symptom of disease to do with a reduction in price, be patient and read on.
跳楼价
Lowest price, junk price, minimum selling price
跳 means jump, 楼 means building, 价 means price. The three add up, means a price so low that the seller rather jump off a building (and not from the ground floor or the first floor) than sell the goods at this price. Although it doesn't make much sense. Maybe it means the seller has to jump if the goods still can't be sold at this price?
This is not a localism, anymore. It comes from the southern area of China, but there're banners with this word in the northest province now. I should know, I lived there.
甩卖
Reduction sale, markdown sale, dispose of goods at reduced prices
甩 means toss, throw. Here with 卖 they mean the meanings above. This word is the same as 跳楼价, began as a localism, is used all over China now.
Some words with the same meaning:
大减价 [dà jiǎn jià] price cutting
便宜卖了（廉价出售）[pián yi mài le (lián jià chū shòu)] go cheap
削价 [xuē jià] cut prices, lower the price
处理 [chǔ lǐ] sell at reduced prices (Usually means handle, deal with, treat)
So, if you ever see these words on a banner or something, it means the goods are on sale.
About the thing that brings these out, well I went to a human resources market today. And I got exactly zero chance. Although it's not my fault, they don't want somebody who will graduate at next July, they want somebody can say "yes" and go to work tomorrow, maybe this afternoon.
All that make me think about the spring in 2003, when my schoolmates ran all around to apply for jobs. We used to joke about it, "Sale! Sale! Human for sale! University man on sale! Junk price! Won't regret it!" Which include all these words above.
And when everyone got a job, or at least some place to go, we used those words to sell our used books.
