Welcome to our English Corner. It set up about four years before. Since then on many high school students have joined in it. The students from different schools gather round on Sunday mornings, and there are also some college students or foreigners. We talked about everything we know and show interest in. We also exchange our effective method in English learning. We think we have learned much here.
