The name of the police is corn, which is a network language formed by imitating the language of Hong Kong and Taiwan. The mainland is called the police uncle, and the uncles in Hong Kong and Taiwan are called corn, so it is more popular on the Internet. Uncle and Xiaomi have roughly the same meaning. Xiaomi is a new word appearing on the Internet now. Similar internet terms refer to soldiers' brothers, little sisters and little girls. Although the network language is not a formal language, it has a certain audience through the spread of the network.
