Therefore,in this book,the main argument is that the technology-enabled English virtuality creates an opportunity for all the Chinese learners or teachers of English to pursue a self-directed cross-cultural social learning and experiment with citizen diplomacy. We have five assumptions not yet fully tested. First,a regular engagement with the English virtuality will largely reduce Chinglish and thus facilitate the acquisition of the English language. Second,a fuller exploration of the English virtuality will better familiarise us with their social practices,thus making better preparation for cross-cultural communication or citizen diplomacy.Third,a regular communication with the ESL/EFL professionals in the English virtuality will benefit the development of English teachers. Fourth,citizen diplomacy will in return keep learners or teachers of English engaged with the English virtuality. Fifth,responsible citizen diplomacy will help better tell Chinese stories,resist the anti-China narratives or improve the international image of China,securing peace for the world. So the purpose of using the English virtuality is not just about English learning or teaching; it is also about citizen diplomacy,making friends,defending China and maintaining peace.
