Li Guangda, a volunteer at the 18th Shanghai Cooperation Organization Summit, said he has received many thumbs-up from foreign reporters for his professional and friendly assistance since he began serving at the information desk of the summit's media center.

"It's very rewarding. For many participants of the summit, our volunteers are the first people they meet and have close contact with. Our behavior matters a lot," said the 22-year-old student from Qingdao-based China University of Petroleum.

Li is one of the 2,000 student volunteers recruited from 10 universities in the coastal city, which is hosting the summit on Saturday and Sunday.

Besides the student volunteers, another 18,000 volunteers from all walks of life have also been providing services around Qingdao.

Because the student volunteers wear blue and white uniforms, they are nicknamed "little sea splashes". They have been mobilized to offer various services for the summit, such as assistance to guests with arrival and departure, translation and media requests.
