In the 16th century, Ming Dynasty (1368-1644) blue porcelain traveled on trading vessels from China and was introduced in the Netherlands, the center of European trade at that time. The Chinese workmanship and attention to detail impressed many and inspired local craftsman to produce similar ceramics. In doing so, they adjusted the production process, patterns and shapes. This evolved into the iconic Delftware as it is today.

Pieter Jan Teisman, a floral designer who told the stories behind Delftware, said the designs represent the interconnectedness of the Netherlands and China.

During the expo's opening ceremony, NBSO Qingdao donated 2,400 tulip bulbs of four different varieties in orange and red to the city of Qingdao as a gift of friendship.

"Our business cooperation is strong and diverse and our friendship is rooted deep in the minds and hearts of our people," said Zeng Ming, chief representative of NBSO Qingdao.

"Qingdao citizens can expect to enjoy the beautiful blooming tulips next year," she added.
