With a theme of "live green, live better", the expo will feature green materials and technologies including rainwater recycling, natural ventilation and solar power to create a green expo park with low energy consumption.

"The expo zone is projected to be a permanent habitat for thousands of flowers and plants," said Zhou. "It will be built into a tourist destination for leisure tourism and an ideal place for ecological education," he said.

His words were echoed by Lu, "The 2019 Beijing Expo is not only an international horticultural exhibition, it's an expo with a mission to help the development of green industries such as leisure, agriculture and sports."
