During the Spring Festival, people who visit relatives and friends in Zhumadian City, Henan Province, received a prompt message from the Zhumadian Anti-Telecom Network Fraud Center. This is a scene of Henan Province's public security organs carrying out prevention of telecommunication network fraud.
