China High-Speed Railway Security Check – What You Need to Know as a Foreigner
As you may know, I was browsing this forum to learn English and conduct market research. Maybe because it's a unique and interesting transportation system in China, high-speed railway questions have been asked quite often. So, I wanted to write this post to help out our foreign friends!
First, something special for you foreigners: ID Check: Most stations require manual verification of passports. However, some upgraded stations (e.g., some on the Hainan Ring Railway and Guangshen High-Speed Railway) support direct passport scanning at the gates. If you're unsure, just follow the signs or ask staff for the manual channel.
Then, a couple of special reminders: Arrive at the station at least 45–60 minutes before departure. If you are fluent in Chinese and familiar with the process, 30 minutes will be enough. Your passport will be checked both at the station entrance and at the boarding gate. (We Chinese citizens use our ID cards for the same process).
Finally, here is the main part: the official rules from 12306.
🚫 What You CANNOT Bring at All (Not in your bag, not in checked luggage) ·Guns, ammo, or anything that looks like a real gun. ·Knives, daggers, crossbows, or any blade/weapon controlled by law. ·Fireworks, firecrackers, gasoline, diesel, or any fuel. ·Alcohol stronger than 70% by volume. ·Self-heating food (the kind with a heat pack – they react with moisture and can catch fire). ·Poisons, strong acids (like sulfuric acid), strong alkalis (like lye), or radioactive materials. ·Infectious stuff – like dangerous germs or viruses. ·Live animals (except guide dogs). Small pets can be checked as luggage if you have a health certificate and a proper carrier. ·Anything that smells really bad (even if sealed – yes, durian and sticky tofu count), or anything that might scare other passengers. ·Any item that security can't figure out but looks risky. 🧳 What You CANNOT Carry On, But CAN Check as Luggage ·Kitchen knives, scissors, or blades longer than 60mm (about 2.4 inches). ·Professional knives (like scalpels). ·Sports gear like bats or clubs. ·Tools like drills, axes, or farm tools. ·Bows, slingshots, or similar items. ·Small pets (as above – with papers and carrier). ⚠️ What You CAN Bring, But With Limits ·Alcohol – Only if it's sealed, clearly labeled, and between 24% and 70% alcohol. Max total: 3 liters (about 100 fl oz). No loose/bulk alcohol. ·Sprays (aerosols) – Like hairspray or sunscreen. Each can ≤150 ml (5 fl oz), one per type, total ≤600 ml (20 fl oz). ·Flammable liquids (non-spray) – Like perfume or bug repellent. Each bottle ≤100 ml (3.4 fl oz), one per type. ·Power banks – Must have clear labeling—each ≤100Wh (about 27,000 mAh). No limit on how many, but must be for personal use. No damaged or unlabeled ones. ·Lighters – Max 2 (no kerosene lighters). Matches – Max 2 small boxes. ·Nail polish & remover – Total ≤50ml (1.7 fl oz). ·Small seafood – Like fish, shrimp, or crabs – OK if in sealed containers. 📏 Baggage Size & Weight ·Weight: Adults ≤20 kg (44 lbs), children ≤10 kg (22 lbs). ·Size: On high-speed trains (D, G, C): length + width + height ≤ 130cm (51 inches). On regular trains (K, T, Z, etc.): ≤ 160cm (63 inches); pole-shaped items ≤ 200cm (79 inches). 🔍 At the Security Check ·Every bag goes through the X-ray machine. ·Liquids, power banks, and some other items may need to be taken out or opened for checking. (Tip: Pack these items in an easily accessible place so you can grab them quickly.) ·If you refuse the check, you won't be allowed in. 🚨 What Happens If You Break the Rules ·Banned items – Confiscated, and police may be called. ·Over-limit items – You have a few choices: Check them as luggage (if allowed). Hand them to someone seeing you off. Store them at the station (free for up to 3 days). Send them via express delivery. Throw them away. 🚜 A Special Note for "Slow" Trains Some slower, public-service trains in rural areas have different rules – they may allow small farm tools and a few live birds/animals. This only applies to those specific trains.

correcting little grammar, haha. Not important but for fun
However, some upgraded stations (e.g., some on the Hainan Ring Railway and Guangshen High-Speed Railway) support direct passport scanning at the gates.
don't think need to say "the" gates. 两个都可以，我觉得
If you're unsure, just follow the signs or ask staff for the manual channel.

manual channel有点不自然，我觉得。可是我也不知道怎样说哈哈。到“ask the staff” 也可以
If you are fluent in Chinese and familiar with the process, 30 minutes will be enough./ it will take only about 30 minutes

Overall feedback
我还没去过中国，可是我也怕。我的母语是中文可是不太好哈哈。
谢谢你！ 没什么好怕的，早点儿到火车站，然后有事问工作人员就好了。他们知道的比我这里列举的更详细了。 另外，你的中文还可以啊。
谢谢哈哈。我有些朋友在新加坡读书但父母在中国。可能会有一天跟他们一起回去❤️
I've used AI to help compile these rules to make them as clear as possible.

Sorry, I’m not interested in correcting AI output, so I’ll just add a few comments here & there.
Thank you for the comments! Just to clarify, I wrote the outline and the part before 'the official rules from 12306'. Since 12306 is the official platform (including a website, an app, and a hotline) with countless detailed rules across different scenarios on different webpages—kind of like a law book—I used AI to help me compile them.
Then I would recommend moving the AI note to the beginning of the section where you describe the rules: “I’ve used AI to compile the following rules from the official website, 12306,…” In general, the attitude towards AI in the West is rather negative right now, so mentioning your AI use will make people trust you less. In fact, many people would be more inclined to trust the information you’re providing if you told them you’d read through the whole website and used your own brain to compile the info!
Thanks again for all the detailed feedback! That's really interesting about the attitude towards AI. I can really sense that from your description. Actually, I did personally read through the whole website in both Chinese and English versions -- that's another reason I decided to write this post. The English version is way too simple compared to the Chinese one. Then, I used my own brain to compile the rules. After that, I found there were several omissions when I double-checked those items. That's when I decided to use an AI to help me.--In China, if you let the AI do all the job, that would be negative. But if you use it like a tool, to check your work, and you also check the output from the AI--like I did here--it's totally ok. Thanks for letting me know the differences. Have a nice weekend!
The method you used makes sense and I think most Western readers would support it, but the sentence “I've used AI to help compile these rules to make them as clear as possible” gives me the impression that you let AI write all of it for you. Instead, I would suggest something like, “After reading through all the rules in both Chinese and English, I compiled the following summary, used AI to check for omissions, and then filled in the gaps myself.”
As you may know, I was browsing this forum to learn English and conduct market research.

Which forum are you referring to?

Calling your readers “you foreigners” sounds unfriendly.
Thanks for the feedback! I honestly didn't realize 'foreigners' could come across as unfriendly. Could you suggest what would sound friendlier here? I'm a bit confused because I always thought 'foreigner' was a neutral word.
In this context, I would change “you foreigners” to “foreign travelers” or “non-Chinese citizens.” “Foreign” (adjective) is neutral in many contexts, but “foreigner” (noun) is often negative, depending on the context, speaker’s tone, and prejudices of the listener. Adding “you” in front of “foreigners” makes the term more likely to be interpreted negatively (or maybe sarcastically), in my opinion. Of course, foreigners who spend much time in China get used to being called “foreigner” and “老外”. Some quickly realize that there’s usually no negative intent behind Chinese people’s use of these terms, but I know Westerners who’ve spent a decade or more in China and are still rankled by “老外”! They’re often the sort of people who manage to live in a country for years but never bother to learn the local language. 🙄
ID
No change suggested
I would recommend changing this to “Passport Check”, since, if I’ve understood correctly, even Chinese nationals have to submit to an ID check, but only foreign travelers have to show their passports.
I’ve added a new comment about “ID Check.”
Finally, here is the main part: the official rules from 12306.

What in the world is 12306?! :-)
·Alcohol – Only if it's sealed, clearly labeled, and between 24% and 70% alcohol.
No change suggested
So if it’s beer (typically around 4% alcohol), wine (11%), or port (~20%), you can’t bring it—it must be at least 24% alcohol?
Great catch! I didn't phrase that clearly. Alcohol under 24% (such as beer and wine) is allowed without special volume limits, as long as it complies with standard baggage rules. And anything over 70% is banned.
Ah, that makes sense!
No loose/bulk alcohol.
No change suggested
“Loose/bulk” can’t be the right term—how can a liquid be “loose”? :-))
AH, I was in a Chinese mindset here! How do you naturally say '散装酒' in English?
I don’t think I’ve ever encountered the term “散装酒” before, so I’m not entirely certain of its implications, but guessing from the context, maybe a statement like this would work: “alcohol must be in its original, labeled, sealed container.”
