Learning Objective: Students can briefly introduce WeChat. Students can describe the impact of WeChat on the lives and social life of Chinese people or themselves. WeChat (WeChat) is an instant voice messaging software launched by Tencent in 2011. Not only can users quickly send voices, videos, pictures and texts through their mobile phones, but they can also share content they especially like, to WeChat Moments. In addition to providing functions such as an official account, Moments and News Push, WeChat can also add friends and follow a public platform through "Scan", "Search Number", "People Nearby", and "Scan QR Code". In addition, WeChat’s “red envelope” payment function combines banking and social networking, and users in China can transfer money to other people or receive money. WeChat has been fully integrated into the everyday lives of Chinese people.
