The International Horticultural Exhibition 2019 Beijing, the largest expo of its kind in the world, opened to the public Monday in Yanqing District. The expo brings together participants from over 110 countries and international organizations as well as over 120 "non-official exhibitors," which present innovative forms of green development in the 503-hectare expo site and open a new chapter in the expo's history with the highest-ever attendance.

The International Pavilion, which covers a total construction area of 22,000 square meters, serves as an indoor exhibition venue for participating countries, regions and horticultural organizations in the international arena.

Features a sea of flowers and zigzagging streams, blossoms are weaved into 94 umbrellas to create a sea of flowers. This floral ocean opens up as an enormous sunshade, shielding the area from the summer heat to provide a pleasant recreational area. When night falls, the floodlights on the umbrella leaves create a colorful night scene for the stadium.
