    Two days ago China held the G20 Leaders Summit (峰会) in Hangzhou. Leaders of the G20 members not only talked about the world issues, but also had a taste of Chinese culture.

    The logo of the summit shows Chinese architectural (建筑) culture. The logo looks like a bridge. “I got the idea from the old arched bridges (拱桥) at the West Lake,” said the designer Yuan Youmin. “Bridge link (连接) people and places in many different ways, just as the G20 brings east and west together.”
