A Huangpu River cruise tour serving the 10th China Flower Expo debuted today, taking about 150 passengers to Chongming Island, as the city's latest efforts to make the iconic river cruise a world-class attraction. The expo, themed “Blossom with a Chinese Dream,” will be staged in Chongming District from May 21 until July 2, the first flower expo to be held on an island. The one-day tour set sail from Qinhuangdao Road Pier in Yangpu District in the early morning and comes with two meals, including a night buffet.
