The 10th China Flower Expo kicked off in Shanghai's Chongming District on Friday. The 666-meter-long, 60-meter-wide axis, connecting the north and south of the pavilion area, features flower bridges to celebrate the 100th anniversary of the Communist Party of China in 2021. CGTN's Chen Tong takes you on a "flower journey" at the Century Pavilion. It is one of the highlights at the expo, with a lower-covered building, outlined in the form of flowers, green plants and gardens, shaped like a butterfly on a peony flower.
