据初步调查

You usually place this phrase right at the start of your sentence. It acts as a frame for the information that follows. Think of it like a header in a professional email. You do not need complex grammar to make it work. Just say 据初步调查 and then follow it with your discovery. For example, 据初步调查，这是系统故障。 (According to preliminary investigation, this is a system failure.) It works best when you have some evidence, even if it is small. You are setting expectations for your audience. You are telling them, "Stay tuned, more details are coming." It is very common in written reports. However, you can use it in speech to sound more objective. It is like putting on a professional blazer over your casual thoughts. Just be careful not to use it for things that are too personal. You wouldn't say "According to preliminary investigation, I like this tea." That would be a bit too much drama for a Tuesday afternoon!

This phrase sits firmly in the "formal" to "neutral" category. You will see it every single day on news sites like Sina or CCTV. It is the bread and butter of official announcements. If a company has a data leak, they will use this. If there is a traffic accident, the police will use this. In a corporate Zoom meeting, it sounds very professional. It shows you are following a process. You aren't just guessing; you are "investigating." On social media, you might see it used by tech leakers or news aggregators. It gives their posts a "breaking news" vibe. It is rarely used in very casual texting between close friends unless you are being funny. If you text your mom 据初步调查 about why you are late, she might think you’ve been watching too many detective shows. It is a tool for credibility. Use it when the stakes are high or when you want to sound like the adult in the room.

Let's look at how this pops up in the wild. On a tech blog, you might read: 据初步调查，新款手机的发热问题与软件更新有关。 (According to preliminary investigation, the heating issue of the new phone is related to the software update.) This protects the blogger if the hardware is actually at fault later. In a neighborhood WeChat group, someone might post: 据初步调查，停电是因为电缆维修。 (According to preliminary investigation, the power outage is due to cable maintenance.) It sounds much more reliable than just saying "I think it's the cables." You will also hear it in Netflix subtitles for any crime drama. When the lead detective arrives at the crime scene, they almost always start their briefing with this. It is the universal signal for "I have the facts, but I'm still looking for the truth." Even in gaming, when a server goes down, the official Twitter account will often tweet this phrase. It buys them time while they fix the bugs.

Use this phrase when you are reporting facts that might change. It is perfect for work emails when a project is delayed. It is great for social media if you are sharing news you just heard. Use it when you want to sound objective and unbiased. It is also a fantastic way to handle pressure. If your boss asks "Why did the client cancel?" and you don't fully know, you can say, 据初步调查，是因为预算调整。 This shows you are already on top of it. You are investigating. You aren't just standing there with a blank stare. It is also useful in academic writing or case studies. It signals the "initial phase" of a study. Basically, use it whenever you want to bridge the gap between "I have no idea" and "I am 100% certain."

Do not use this for your personal feelings or opinions. Saying 据初步调查，我不喜欢这个人 (According to preliminary investigation, I don't like this person) sounds like you ran a background check on a blind date. It is way too cold. Also, avoid it for very simple, obvious facts. If you see it's raining, don't say 据初步调查，外面在下雨。 People will think you are a robot. It requires an element of "investigation." If no effort was needed to find the fact, the phrase feels misplaced. Don't use it if you are absolutely certain and have all the final proof. At that point, use 经调查确认 (confirmed by investigation). Using the "preliminary" version when you know the final answer can make you look indecisive. It’s a tool for uncertainty, not a way to hide from the truth. Keep it for the "maybe" and "early" stages of a story.

A very common mistake is forgetting the 据 (jù). Learners often just say 初步调查..., which sounds like a title rather than a sentence opener. Remember: ✗ 初步调查，那是他的错 → ✓ 据初步调查，那是他的错. Another mistake is mixing up 初步 (chūbù - preliminary) with 第一 (dìyī - first). While it is the "first" investigation, 初步 is the specific professional term. Also, don't use it for things that happened a long time ago. If something happened last year, it's no longer "preliminary." ✗ 据初步调查，秦朝在1990年灭亡 → ✓ Well, that's just historically wrong! But you get the point. It is for current, developing situations. Finally, don't over-rely on it. If every sentence you say starts with this, you'll sound like a broken news ticker. Variety is the spice of life, even in investigations!

You might also see 根据初步调查 (gēnjù chūbù diàochá). It means exactly the same thing but feels a tiny bit more formal because of the extra syllable. 据 is just the short, punchy version. Another variation is 据初步统计 (jù chūbù tǒngjì), which means "according to preliminary statistics." Use this when you are dealing with numbers or data. If you are talking about what you heard people saying, you might use 据初步了解 (jù chūbù liǎojiě), which means "according to preliminary understanding." This is slightly softer and less "detective-like." In very formal documents, you might see 据初步核实 (jù chūbù héshí), which means "according to preliminary verification." This implies you’ve actually checked some documents or IDs. Each variation shifts the focus slightly, but they all share that "initial report" DNA.

Is it okay for casual talk? Only if you are being a bit dramatic or professional for fun. Otherwise, stick to 我听说的 (I heard that). Can I use it in an essay? Yes, it is perfect for the introduction of a report or a case study. Does it mean I'm not sure? It means you have some facts, but you are leaving the door open for new information. Is 据 mandatory? Yes, in this specific construction, 据 provides the "according to" meaning. Without it, the sentence doesn't flow correctly. It is a small word with a lot of heavy lifting. Think of it as the anchor that holds the whole investigation together. Now go forth and report your findings with confidence!
