Ladies and gentlemen,
Welcome to our English Corner. The English Corner was set up by some English teachers and students ten years ago. Every Saturday evening from 7:30 pm to 9:00 pm, students from different schools nearby gather here. In our English Corner, we can practice our oral English and improve our English abilities. At the same time, we also meet a variety of people here, including some foreign friends. So we can use English Corner to make new friends and increase our knowledge. Usually we choose a topic for participants to discuss and we also organize activities, such as singing English songs and playing English games. So enjoy yourself here. Thanks.
