The Mandarin Chinese phrase '据说 (jùshuō)' is used to introduce a hearsay or to convey an information that is said to be true but which the speaker doesn't have personal confirmation or doesn't personally witnessed. It is often used when sharing news, stories or rumours, and is equivalent to the English expressions 'it is said that', 'reportedly', 'apparently'. The usage is widespread in both written and spoken Chinese.
