Did the personnel in Xianyang really receive the news of Xi 'an epidemic prevention and control?

No, the reminder SMS is a risk reminder for people who are judged to be exposed in places related to the epidemic after cell phone signaling investigation and big data analysis. Xianyang is a prefecture-level city under the jurisdiction of Shaanxi Province, bordering Xi 'an, the provincial capital, in the east. Reminder SMS will only send big data to people in the same area. It is not true to receive the short message from Xi, because Xi and Xianyang are two regions in Shaanxi Province.
