§Text Passage
1Information has never been so abundant, nor so hard to judge. Research finds fake news spreads several times faster than true news on social media — sensational content triggers sharing. Three motives drive fake messages: earning clicks and ad money, stirring emotions and conflict, and fraud. During the epidemic in Hong Kong, a rumour that 'supermarkets will close completely' once triggered panic buying; others received phishing messages posing as banks or government bodies and lost personal data. In this flood, media literacy matters as much as reading and writing.
2First, learn the common tricks. 'Clickbait' lures clicks with exaggerated headlines that the content never matches. Quotes 'out of context' slice one sentence so the meaning flips. 'Transplanted' posts match old photos or foreign events to new news — a flood photo from years ago presented as yesterday's typhoon. AI-generated deepfakes can make famous people 'say' words never spoken. Charts can lie too: a cropped axis makes a small gap look like a chasm. Add 'Shocking!' and 'Share fast!' emotional hooks, and we forward before thinking.
3Fact-checking has five steps. One, check the source: who posted it? Is there a name, a date, a credible body? Treat anonymous group messages with doubt. Two, ask the motive: does it seek clicks, stir anger, sell something, or harvest data? Three, cross-check: have at least two independent, reliable outlets reported it? Four, reverse-search the image: is the photo old or from another event? Five, consult authorities: official government sites, trusted media and fact-checking organisations. After five steps, most rumours collapse.
4After checking comes the duty of sharing. Forward nothing uncertain — 'let the bullet fly a while' until officials and trusted media verify. Warn family and classmates about rumours and report them on the platform. Treat any message asking for passwords, codes or transfers with alarm: verify directly with the official body, and call the police if needed. Teach these methods to elders at home, for they are prime targets of scams and rumours. In the digital world every forward is a statement: verifying before sharing keeps the information environment healthy.

3Step by step Steps
- Step 1: Check the sourceBefore trusting any message, first check its source: who sent it, when, and whether a credible body stands behind it. Example: a group message says 'citywide water cut tomorrow' with no name, no date, from an anonymous account — mark it doubtful instead of forwarding. Unverified sources deserve automatic doubt; and a forward from a friend only means the friend believed it, not that it is true, so still verify it yourself.
- Step 2: Ask the motiveNext ask what the sender wants: to inform you, to persuade you, or to take your money? Example: the message ends 'forward to ten groups' with a shopping link — stirring shares plus selling; a suspicious motive says pause. Messages that stoke panic or push you to act fast often hide another purpose; the more urgent the tone, the calmer you should stay, and asking 'who benefits' avoids most of the traps.
- Step 3: Cross-check independent sourcesReliable news is covered by several independent sources; text circulating in only one place is suspect. Example: search the claim: two major papers and the water authority's site report nothing, while the same text circulates in many groups — a classic rumour sign. Compare at least two or three unrelated sources, and check whether reports name their sources and dates, for recycled old news is often mistaken for a fresh event.
- Step 4: Reverse-search the imageImages are easily transplanted, and a reverse image search reveals where a picture truly came from. Example: a 'yesterday's typhoon flood' photo is searched by image and first appeared five years ago in another typhoon — the transplant is exposed. Old photos with new stories are among the most common tricks; even when the original cannot be found, details in the picture — shop signs, clothing, seasons — that contradict the claim give good grounds for doubt.
- Step 5: Consult authorities and reportFinally, verify with authoritative bodies, and once a rumour is confirmed, act responsibly. Example: confirm on government press releases and fact-checking sites that it is false, report it on the platform, and warn the group not to spread it. Government sites, trusted media and checkers keep updated debunk pages; attach the link when telling others, so the correction rests on evidence. Reporting and debunking are duties of a digital citizen.
- Step 6: Spot misleading charts and dataCharts look objective, yet they can be doctored to mislead readers. Example: a bar chart starts its axis at 98, turning a 2-per-cent gap into a seeming threefold difference — check the axis origin and sample size before concluding. Even true data mislead when the sample is tiny or cherry-picked; behind a dramatic contrast, ask for the source, the survey date and how the figures were counted.
- Step 7: Bear the duty of sharingBefore every forward we are answerable for the truth of the content, because forwarding is itself spreading. Example: a 'bank SMS' asks for a verification code; do not tap the link, call the bank's official line, and report to the police if it is a scam — then warn elders at home. One minute of checking before sharing beats an hour of clarifying afterwards; verifying before sharing protects yourself and others.

5Worked example Example
Example: a classmate forwards this to the class group: 'All supermarkets close tomorrow morning because of the typhoon — rush out tonight!' with a photo of emptied shelves. Analyse it with the five fact-checking steps.
- Source: no name, an unknown account, no date or body cited — the first alarm rings.
- Motive: 'rush out tonight' stirs panic and pushes action, with a photo for persuasion — a clear emotional trigger.
- Cross-check: news search shows only typhoon signal 3 raised; no outlet reports all supermarkets closing, and no government notice exists.
- Image check: reverse image search finds the photo was taken years ago in another storm, not in Hong Kong recently.
- Conclude and act: judged a rumour — remind classmates not to forward, post the verification results in the group, and report the message on the platform.
- Answer: The five steps show an unclear source, an inflammatory motive, no reliable coverage and an old photo — a rumour. Do not forward; debunk in the group and report it, rather than joining the panic buy.
