What is the drooling emoji?

Emoji, originally just a network subculture, has been widely accepted by the society with the popularity of the Internet and mobile phone short messages. Later, many communication programs (especially real-time communication programs) and forums began to express their feelings with more vivid small icons. Therefore, at the end of the 20th century, a new word to explain these emoji appeared in English, that is, Emotion and small icon were skillfully combined to form the new word "emotion". In Japanese, the Chinese character "Yan Wen Zi" (Japanese: かぉもじ Yan Wen Zi) is used to address emoticons, meaning face, while "Yan Wen Zi" uses words and symbols to express the writer's mood, which is gradually adopted by young people in Taiwan Province Province and Hong Kong.
