• Keywords: tuoshui, 脱水, dehydrate in Chinese, dehydration in Chinese, what does tuoshui mean, dried food Chinese, Chinese internet slang, remove filler content Chinese, tl;dr in Chinese, 脱水版
• Summary: “脱水” (tuōshuǐ) is a versatile Chinese term whose core meaning is “to dehydrate” or “dehydration.” It is used literally in medical contexts to describe the loss of body fluids and in food processing for things like dried fruit. In modern internet culture, it has gained a popular slang meaning: “to remove the water,” which means filtering out filler, spam, or irrelevant comments from an online post or thread to get to the core, substantive content (the “dry goods”).

• Pinyin (with tone marks): tuō shuǐ
• Part of Speech: Verb, Noun
• HSK Level: HSK 5
• Concise Definition: To lose or remove water; dehydration.
• In a Nutshell: “脱水” literally translates to “take off water.” Think of it as separating the water from something else. This can be a serious medical condition (your body losing too much water), a simple food preparation method (making dried mangoes), or a useful internet action (creating a “dehydrated version” of a long forum post that only contains the important information).

• 脱 (tuō): This character means “to take off,” “to shed,” or “to escape.” Imagine taking off a coat (脱外套 - tuō wàitào) or a snake shedding its skin. It implies removal or separation.
• 水 (shuǐ): This is one of the most basic characters, simply meaning “water.”
• The two characters combine quite literally: 脱 (to take off) + 水 (water) = 脱水 (to remove water, dehydrate).

While the literal meaning of “脱水” is scientific and universal, its figurative use in modern Chinese internet culture offers a fascinating glimpse into digital life. In this context, “脱水” is the antidote to “注水” (zhùshuǐ - to inject water), which means flooding a post, story, or TV show with filler, spam, or meaningless content to inflate its length or engagement metrics. Chinese internet users value efficiency and “干货” (gānhuò - dry goods), meaning content with real substance. When a popular forum thread becomes thousands of comments long, users will often ask for a “脱水版” (tuōshuǐ bǎn - dehydrated version). This is a version of the thread where a helpful netizen has filtered out all the “I agree,” “lol,” and off-topic conversations, leaving only the original poster's updates and other high-value comments. This is similar to the Western concept of “tl;dr” (too long; didn't read), but with a key difference: a “tl;dr” is usually a summary provided by the author at the beginning or end. A “脱水版,” however, is often a community-driven effort to curate and clean up a long, messy conversation for everyone else's benefit, reflecting a collective desire for clarity and substance.

The connotation of “脱水” depends entirely on the context.

Here, “脱水” is a neutral, clinical term for dehydration. It's used by doctors, in health articles, and in everyday conversation about health. The connotation can be negative if referring to a dangerous medical state.

This is a neutral, technical term for the process of removing water from food or other materials. “脱水蔬菜” (tuōshuǐ shūcài) are dehydrated vegetables.

In this very common, informal usage, “脱水” has a positive and practical connotation. It refers to the desirable act of filtering out noise to get to the signal. Asking for a “dehydrated” version is a request for a high-quality summary.

• Example 1:
  • 医生说我有点儿脱水，需要多喝水。
  • Pinyin: Yīshēng shuō wǒ yǒudiǎnr tuōshuǐ, xūyào duō hē shuǐ.
  • English: The doctor said I'm a bit dehydrated and need to drink more water.
  • Analysis: This is the most common literal, medical usage. “脱水” is used here as a noun (dehydration).
• Example 2:
  • 夏天运动后要及时补充水分，以防脱水。
  • Pinyin: Xiàtiān yùndòng hòu yào jíshí bǔchōng shuǐfèn, yǐ fáng tuōshuǐ.
  • English: After exercising in the summer, you should replenish fluids promptly to prevent dehydration.
  • Analysis: Here, “脱水” is again used as a medical noun. The structure “以防…” means “in order to prevent…”
• Example 3:
  • 这种方便面里的蔬菜是脱水蔬菜。
  • Pinyin: Zhè zhǒng fāngbiànmiàn lǐ de shūcài shì tuōshuǐ shūcài.
  • English: The vegetables in this instant noodle packet are dehydrated vegetables.
  • Analysis: This shows the food processing context. “脱水” acts as an adjective describing the vegetables.
• Example 4:
  • 这个论坛帖子太长了，有没有人能发个脱水版？
  • Pinyin: Zhège lùntán tiězi tài cháng le, yǒu méiyǒu rén néng fā ge tuōshuǐ bǎn?
  • English: This forum thread is too long, can someone post a “dehydrated” (condensed) version?
  • Analysis: A classic example of the internet slang usage. “脱水版” (tuōshuǐ bǎn) means the condensed version with all the filler comments removed.
• Example 5:
  • 我只看楼主的脱水版，不想看其他人的回复。
  • Pinyin: Wǒ zhǐ kàn lóuzhǔ de tuōshuǐ bǎn, bùxiǎng kàn qítā rén de huífù.
  • English: I'm only reading the “dehydrated” version with just the original poster's comments, I don't want to see other people's replies.
  • Analysis: This specifies a common type of “dehydrated version”—one that only includes posts from the “楼主” (lóuzhǔ), the original poster or thread creator.
• Example 6:
  • 呕吐和腹泻很容易导致儿童脱水。
  • Pinyin: Ǒutù hé fùxiè hěn róngyì dǎozhì értóng tuōshuǐ.
  • English: Vomiting and diarrhea can easily lead to dehydration in children.
  • Analysis: Another serious medical context. “导致” (dǎozhì) means “to lead to” or “to cause.”
• Example 7:
  • 宇航员的食物很多都是经过脱水处理的。
  • Pinyin: Yǔhángyuán de shíwù hěnduō dōu shì jīngguò tuōshuǐ chǔlǐ de.
  • English: A lot of astronauts' food has been processed through dehydration.
  • Analysis: This uses “脱水” as a verb within the structure “经过…处理” (jīngguò…chǔlǐ), meaning “processed through…”
• Example 8:
  • 感谢10楼的网友，你的脱水总结帮我节省了很多时间！
  • Pinyin: Gǎnxiè shí lóu de wǎngyǒu, nǐ de tuōshuǐ zǒngjié bāng wǒ jiéshěng le hěnduō shíjiān!
  • English: Thanks to the netizen at post #10, your dehydrated summary saved me a lot of time!
  • Analysis: Demonstrates the positive, appreciative tone associated with the slang usage. A “脱水总结” is a “dehydrated summary.”
• Example 9:
  • 这部电视剧剧情太脱水了，一点废话都没有。
  • Pinyin: Zhè bù diànshìjù jùqíng tài tuōshuǐ le, yīdiǎn fèihuà dōu méiyǒu.
  • English: The plot of this TV show is so “dehydrated” (lean/concise), there's absolutely no filler dialogue.
  • Analysis: An interesting and less common slang usage where “脱水” is used as a positive adjective to describe a story or plot, meaning it's tight, concise, and all substance. It's the opposite of a plot that “注水” (is filled with water).
• Example 10:
  • 如果你看到病人有严重脱水的迹象，应该马上送他去医院。
  • Pinyin: Rúguǒ nǐ kàndào bìngrén yǒu yánzhòng tuōshuǐ de jìxiàng, yīnggāi mǎshàng sòng tā qù yīyuàn.
  • English: If you see signs of severe dehydration in a patient, you should send them to the hospital immediately.
  • Analysis: A formal, serious medical sentence. “严重脱水” means “severe dehydration.”

• Verb vs. Noun: “脱水” can be a verb (“to dehydrate”) or a noun (“dehydration”). The context usually makes it clear. For example, “他脱水了” (Tā tuōshuǐ le) - He is dehydrated (verb action). “这是一种脱水症状” (Zhè shì yīzhǒng tuōshuǐ zhèngzhuàng) - This is a symptom of dehydration (noun).
• Context is Everything: The biggest mistake is confusing the contexts. Joking about “dehydrating” a funny cat video is fine. Using the same lighthearted tone when someone is sick and literally dehydrated would be inappropriate.
• Not for Drying Clothes: Do not use “脱水” to mean drying clothes on a line or in a dryer. For that, you use 晾干 (liànggān - to air dry) or 烘干 (hōnggān - to machine dry). However, the spin cycle of a washing machine, which removes excess water, is called “脱水” in that specific context. For example, “洗衣机正在脱水” (The washing machine is in its spin cycle).

• 注水 (zhùshuǐ) - “To inject water.” The direct antonym of the slang version of “脱水,” meaning to add filler, fluff, or fake engagement to content.
• 干货 (gānhuò) - “Dry goods.” The valuable, substantive content that remains after the “water” (filler) has been removed. This is the goal of “脱水.”
• 懒人包 (lǎnrénbāo) - “Lazy person's pack.” A term popular in Taiwan and Hong Kong for a concise summary of a complex topic or news event, very similar in function to a “脱水版.”
• 精华 (jīnghuá) - Essence; the best part. An online post marked as “精华帖” (jīnghuá tiē) is a high-quality post, serving a similar purpose to a “dehydrated” thread.
• 水分 (shuǐfèn) - Moisture; water content. In the literal sense, this is what is removed during 脱水. In the slang sense, it refers to the filler content.
• 中暑 (zhòngshǔ) - Heatstroke. A serious medical condition often caused by or associated with severe dehydration.
• 干燥 (gānzào) - Dry, arid. This describes the state of something after it has been dehydrated.
