China Science engagement report
@ChinaScience - 2.0M followers on X
Measured over 61 original posts from a 30-day window, last computed on August 21, 2026.
Engagement
A typical post picks up 78 interactions against 2.0M followers, an engagement rate of 0.004%. Measured over 61 original posts, its engagement rate beats 30% of 1,003 tracked accounts of a similar size, which puts it in the middle of its size range rather than at either end. Posts are seen about 10K times each, and 0.765% of those impressions turn into an interaction. That is about 0.513% of the follower count, which is the gap between an audience on paper and an audience in a timeline. Posting runs at about 2.1 posts a day over the last 30 days, though only 30% of days saw any activity at all. Most posts go out around 05:00 UTC, and Wednesday is the busiest day of the week. Of the 61 posts sampled, 100% carry an image or video and 10% link out. The account's strongest tracked post pulled 833 interactions, about 11x its own typical post.

Compared with accounts its own size
China Science's engagement rate beats 30% of the tracked X accounts closest to it in follower count (1,003 accounts, accounts of similar size (decile 8 of 10)). A percentile is spread evenly by construction, so 50 really is the middle of that group and 90 really is its top tenth.
On engagement per impression rather than per follower it beats 46% of the same group. When those two numbers disagree, the gap is about how far its posts travel rather than how people react to them.
Where this sits in the catalog
At 0.004%, China Science sits above the 10th percentile of the 10,151 accounts in this comparison. That places it in the bottom 25% band, which runs below 0.007%.

Posting timing
This account posts most often around 05:00 UTC, and Wednesday is its busiest day of the week. The bars below are the catalog-wide pattern, with this account's own busiest slot marked. They do not show how this account performs at each hour: we keep one aggregate per account, not one per hour, so that measurement does not exist in our data.

Formats this account uses
Its own posting mix on the left, and what each of those formats does across every account we track on the right. Only formats where the effect clears our publish test appear here, so an empty row is a format we could not measure rather than one that does nothing.
| Format | This account | Catalog effect | 95% interval | Accounts behind it |
|---|---|---|---|---|
| Image or video | 100% of posts | +79% | +73% to +85% | 5.8K |
| Outbound link | 10% of posts | -49% | -50% to -47% | 6.1K |
| Typical length | - | +13% | +10% to +15% | 6.4K |
- 100% of this account's sampled posts carry an image or video. Across the catalog, posts with an image or video run 79% above the same accounts' other posts.
- 10% of its posts carry a link off X. Across the catalog, posts with an outbound link run 49% below the same accounts' other posts.
- Its average post runs 563 characters, which falls in the over 280 characters band. Across the catalog, posts over 280 characters run 13% above the same accounts' other posts.
These are catalog-wide differences applied to this account's own posting mix, not a measurement of how each format performs for this account specifically. We keep one median per account, not one per format per account, so the second thing is not something this data can tell you.

A giant 'solar power bank' hidden in Gobi Desert, NW China's Xinjiang Can a solar power plant still generate electricity after the sun goes down? In Hami, northwest China's Xinjiang Uygur Autonomous Region, rows of linear Fresnel reflectors track the sun, concentrating sunlight into thermal energy and storing it using molten salt. When night falls, this stored heat can be released to continue generating electricity, functioning just like a giant power bank for sunlight. The integrated project, combining concentrated solar power (CSP) and photovoltaic (PV) technology, has a total capacity of 1 million kilowatts (kW). It consists of a 900,000-kW PV power station and a 100,000-kW linear Fresnel molten salt CSP plant, whose solar field covers approximately 800,000 square meters. From tracking sunlight and storing heat to generating power, solar energy is transcending the boundaries of day and night in the Gobi Desert.

The Chang'e-7 lunar probe is scheduled for launch at an appropriate time, according to the China Manned Space Agency (CMSA). The combination of the Chang'e-7 lunar probe and the Long March-5 Y14 carrier rocket was transferred vertically on Wednesday to the launching area at the Wenchang Spacecraft Launch Site in south China's Hainan Province, the CMSA said. The lunar probe and rocket had arrived at the launch site in April and July, respectively, and have since completed assembly and testing. The CMSA said all facilities and equipment at the launch site are in good condition, and the functional checks, joint test and propellant filling will be carried out before the launch as scheduled. The Chang'e-7 mission aims to achieve breakthroughs in multiple key technologies, such as high-precision soft landing on the lunar surface, legged movements, hopping and exploration of permanently shadowed craters. According to the CMSA, the mission will employ a comprehensive detection approach, which involves orbiting, landing, roving and hopping to conduct environmental and resource surveys of the lunar south pole. It will also involve international cooperation.

Chinese scientists have discovered an exceptionally well-preserved pregnant specimen of a 244-million-year-old ichthyosaur Mixosaurus, containing at least 11 fetuses, in southwest China's Guizhou Province. The discovery sets a new record for the most embryos found in a Triassic ichthyosaur and reveals that high reproductive capacity in ichthyosaurs evolved earlier than previously believed.

In a first, Chinese astronomers have discovered that the Milky Way is not a simple, smoothly warped disk, but contains widespread "wrinkle-like" structures resembling ripples on a water surface after analyzing over 30,000 molecular clouds from the Milky Way Imaging Scroll Painting survey — a Galactic plane CO survey conducted by the Purple Mountain Observatory's 13.7-meter millimeter-wave telescope in China, providing new clues to understanding the galaxy's 3D structure and evolutionary history, according to a paper published in the journal @NatureAstronomy.

A lifebuoy that flies itself to you? Not sci-fi — it’s real! The AI-powered rescue device wowed onlookers at a recent rescue drill in Hangzhou, east China’s Zhejiang, and is now making waves online as a glimpse of how Chinese tech is transforming water rescue. The “flying lifebuoy” is a specially designed drone. It can fly autonomously to people in distress, keep two adults weighing up to 80 kg each afloat, and return on its own after the rescue. Reaching flight speeds of 10–14 meters per second and an operating radius of up to 2,000 meters, the smart lifebuoy is now in use at West Lake.

Reading these numbers
A typical post picks up 78 interactions against 2.0M followers, an engagement rate of 0.004%. Measured over 61 original posts, its engagement rate beats 30% of 1,003 tracked accounts of a similar size, which puts it in the middle of its size range rather than at either end. Posts are seen about 10K times each, and 0.765% of those impressions turn into an interaction. That is about 0.513% of the follower count, which is the gap between an audience on paper and an audience in a timeline. Posting runs at about 2.1 posts a day over the last 30 days, though only 30% of days saw any activity at all. Most posts go out around 05:00 UTC, and Wednesday is the busiest day of the week. Of the 61 posts sampled, 100% carry an image or video and 10% link out. The account's strongest tracked post pulled 833 interactions, about 11x its own typical post.
- What is China Science's engagement rate on X?
- China Science (@ChinaScience) has an engagement rate of 0.004%, based on the median interactions across 61 original posts from the last 30 days against 1,986,756 followers. Replies, reposts and quote-posts of other people are excluded from that sample.
- Is that a good engagement rate?
- At 0.004%, China Science sits above the 10th percentile of the 10,151 accounts in this comparison. Those comparison accounts are all large ones, because our scanning cadence is weighted towards big accounts, so this is a ranking among peers of similar scale rather than a ranking across X.
- Does @ChinaScience have real engagement?
- Its engagement rate beats 30% of the tracked X accounts closest to it in follower count (1,003 accounts), which puts it in the middle of its size range group. Ranking inside a size band matters because engagement rate falls as accounts grow, so a raw rate would mostly re-measure the follower count. It is a starting point for a look at follower quality, not a verdict on it.
- When does @ChinaScience post?
- Most posts go out around 05:00 UTC, and Wednesday is its busiest day, at roughly 2.1 posts per day across the measured window.
