On April 30, dozens of BNAI staff met to exchange English learning tips, which was the first off-line English learning activity of Beijing National Accounting Institute staff interest group on English learning.  Prof. Yang Zhiqiang of the Teaching and Research Center also participated and exchanged experiences with peers on the theme of "Efficient Communication". He introduced "the method of mastering a foreign language", explained the two core concepts of "input" and "output" in language acquisition, and suggested for balanced attention to both "input" and "output" in the process of English learning to achieve good learning results. In the structured discussion session, members of the interest group were divided into teams of 4, each of whom was assigned with one of the roles of a chairperson, a recorder, a timekeeper and a presenter.  Participants burst into laughter from time to time when presenters shared their opinions on the topic of "hobbies" on behalf of the team. At the end of the activity, participants could not help but expecting the next gathering.
