Billboard promoting Expo appears at Time Square

A giant billboard promoting the tourism in China and the Shanghai Expo appears at the Time Square in New York City this week. The billboard will catch the eyes of millions of Americans and foreign tourists thronging the Time Square over the next three months.
First, I think it’s a good way to attract more foreign people to visit the Shanghai World Expo. Second, it can help Expo to increase tourism promotion efforts. Time Square is the best advertising place. Last, it also can further expand China Overseas visitors Resources.
More than 190 countries and more than 50 international organizations have regeistered to participate in the Shanghai World Expo. It will be held in May 1 to October 31.
Welcome to Shanghai.
